Slappin' Glass Podcast

Iowa State Head Coach TJ Otzelberger joins the Slappin’ Glass Podcast to discuss building one of college basketball’s most disruptive defensive identities.

Coach Otzelberger explains why Iowa State prioritizes mentality over scheme, beginning with its commitment to creating a “collision” on the first dribble, pressuring the ball inside the scoring area, and forcing opponents to play under duress. He details the Cyclones’ “goalie” and “spy” responsibilities, early baseline rotations, and the habits required to sustain an aggressive defense.

The conversation also explores the trade-offs Iowa State accepts—including additional three-point attempts, difficult rotation-rebounding situations, and increased physical demands—in exchange for generating turnovers and controlling the possession battle. Coach Otzelberger breaks down their approach to short-roll defense, why they often prefer the opposing five making decisions, and when a skilled big may require a coverage adjustment.

He also discusses competitive endurance and designing practices without lulls, using on-the-fly coaching and continuous competition to reflect the program’s identity.

In Start, Sub, or Sit, Coach Otzelberger shares the in-game information he values most, how he approaches substitutions and closing lineups, and why a head coach’s primary responsibility is refocusing the team on the next possession.

The episode closes with offensive decision-making, how physical defense strengthens offensive habits, adapting identity to different programs, and why the greatest investment a coach can make is being fully present with their players.

In this SG Deep Dive, Dan Krikorian, Patrick Carney, and Eric Fawcett examine how offenses are attacking the hedge-and-plug pick-and-roll coverage that continues to spread throughout European and modern basketball.

The conversation begins with why the coverage has become so effective. Hedge and plug allows the defense to pressure the ball without fully committing two defenders, protect the short roll, and remain compact behind the play. Because many offenses still rely on two quick passes to escape the hedge, defenses have also become increasingly prepared for the rotations that follow.

From there, the group explores ways to create an advantage before the defense can settle. They break down rejecting the hedge, using Gortat screens against the recovering big, flipping or hooking the screening angle, “sticking” the plug defender, and flowing into boomerang rescreens that can turn the original hedge into a drop or switch.

A central theme is the micro closeout faced by the on-ball defender after disengaging to plug the roll. The discussion covers how offenses can attack that vulnerable footwork, along with defensive teaching points involving stance, handwork, jump timing, and calculated risk.

The episode also revisits Dave Collins’ idea of coaching as “informed art.” The group discusses blending cognitive science, ecological dynamics, the constraint-led approach, and predictive processing while still accounting for the players, context, and human feel of coaching.

They close with the European teams and playoff series currently filling their film queues. 

What You’ll Learn

•  Why hedge and plug can create ball pressure while keeping the rest of the defense compact. 
•  How advanced defenses are solving the pick-and-roll two-on-two and preparing for the offense’s second pass. 
•  Why rejecting the hedge can expose the on-ball defender’s moment of disengagement. 
•  How to use Gortat screens, flip screens, and boomerang rescreens against the recovering big. 
•  What the group means by a micro closeout, and why it gives the ball handler an immediate advantage. 
•  Teaching considerations for the plug defender’s footwork, hand positioning, and jump timing. 
•  Why offenses need to generate an advantage inside the initial ball-screen action instead of simply accepting the coverage. 
•  How coaches can blend cognitive science, ecological dynamics, and predictive processing without becoming tied to a single framework. 
•  Why good practices and wins deserve the same level of reflection as poor performances. 
•  Teams and playoff series worth studying across the Spanish ACB and European basketball.

This week on the Slappin’ Glass Podcast, Dan and Pat are joined by International Pro Head Coach and player development specialist Matt Jones for a deep dive into shooting development, coaching communication, and building conceptual offense.

The conversation opens with Jones’ approach to evaluating shooters, beginning with one of his core beliefs: watch the player first. Before over-coaching or over-correcting, Jones discusses the value of being a “quiet eye,” identifying inefficiencies, and helping players simplify their shooting movement. From there, he gets into the details of clean catches, loaded wrists, open palms, shot preparation, and how small mechanical improvements can create real gains at higher levels.

Jones also shares how he uses player feedback, feel-based cues, and individualized terminology to help shooters self-correct. Rather than flooding players with technical language, he explains how the best cues often come from what the player physically feels, giving coaches a more useful way to teach shooting under pressure.

In the show’s Start, Sub, or Sit segment, the conversation shifts to finding your coaching voice as an introvert, where Jones breaks down the importance of preparation, listening, terminology, and getting enough coaching reps to build confidence. The episode closes with a thoughtful discussion on conceptual offense, including re-triggers, offensive talk, cutting rules, late-clock structure, and how to help players find the next action without becoming robotic.

What You’ll Learn

• How Matt Jones evaluates shooters before making mechanical corrections
• Why simplifying a player’s shot can improve repeatability and efficiency
• The importance of clean catches, open palms, loaded wrists, and eliminating wasted movement
• How to introduce variability into shooting workouts without overwhelming the player
• Why feel-based cues can be more effective than over-teaching technique
• How analytics can help shape shooting development without damaging a player’s confidence
• Why free throws can be used as a powerful form-shot reset inside a workout
• How introverted coaches can develop their voice through preparation, terminology, and coaching reps
• Why “your terminology is your culture” when communicating with players
• How conceptual offense depends on cutting rules, spacing, re-triggers, and offensive talk
• Why the player with the ball must think like the point guard in read-based offense
• How random practice environments can help players learn to self-organize late in possessions

This week we’re joined in this SG Classics episode by International Head Coach Francesco Tabellini for a deep dive into the concepts behind his team’s relentless style of play.

Tabellini opens the conversation by unpacking the idea of “canceling the pauses” in the game — eliminating the dead space between offense and defense, defense and offense, and every small conversion moment in between. From there, he details how Nymburk builds pace through first-three-step urgency, no-catch zones, early outlets, transition cutting, and a constant pressure-on-the-rim mentality.

The conversation also explores offensive spacing and cutting principles, including baseline cuts on middle penetration, OKC cuts on baseline drives, shortening the pass, and why player confidence is central to shot selection. Tabellini explains how tagging up not only creates extra possessions, but also supports shooting freedom, transition defense, and full-court pressure.

Later, the discussion moves into the defensive side of the floor, including the details of teaching tagging up, evaluating effort, structuring practice to build habits, and using hedge-and-plug coverage as a temporary switch designed to disrupt rhythm, force decisions, and keep opponents uncomfortable.

What You’ll Learn

•  How Tabellini defines “relentless basketball” and why it starts with removing the pauses between phases of the game 
•  Why the first three steps in transition are a major teaching point for Nymburk 
•  How “no-catch zones,” pitch-aheads, and 28-meter cuts create early dynamic advantages 
•  Why aggressive cutting can solve spacing problems rather than create them 
•  How tagging up can become both an offensive rebounding system and a transition defense tool 
•  Why leaving the tag too early can kill the entire purpose of tagging up 
•  How Nymburk structures practice to reinforce tagging up without overloading players 
•  Why Tabellini views hedge-and-plug coverage as a temporary switch 
•  How slips, flips, and re-screens stress aggressive ball screen coverages 
•  Why activity, effort, and mistake-fixing are central to Tabellini’s coaching philosophy

In this episode, Dr. Andy Galpin joins Slappin’ Glass for a practical, high-level conversation on basketball performance, recovery, strength training, sleep, travel, and pregame preparation.

Galpin breaks down why improving movement is not just about stretching, mobility work, or lifting weights, but about understanding the physical qualities that allow athletes to move with more range, force, control, and efficiency. The conversation moves from the history of strength training in sport to modern tools for evaluating movement, asymmetries, muscle development, and return-to-play readiness.

A major theme of the episode is recovery. Galpin makes a strong case that sleep is still the most powerful performance tool available to coaches and athletes, especially in-season. He discusses the impact of early practices, late-night games, post-practice downregulation, hydration, fueling, protein synthesis, and how coaches can better organize the schedule before fatigue becomes a problem.

During “Start, Sub, or Sit,” the conversation turns to silent stressors inside a basketball program, including travel, walkthroughs, film, scout prep, pregame warmups, physical contact, and how to prepare players to actually feel ready when the ball goes up. 

What You’ll Learn

•  Why strength training can improve movement, range of motion, and athletic expression when it is designed correctly. 
•  How coaches should think about recovery beyond soreness, including sleep, hydration, refueling, and rebuilding tissue. 
•  Why early-morning practices may be costing teams more than they realize. 
•  How post-practice and postgame downregulation can help athletes transition toward better sleep. 
•  Why travel is one of the biggest hidden stressors on player performance. 
•  How to proactively adjust practice loads around dense parts of the schedule. 
•  What coaches should consider with bus rides, compression gear, movement breaks, and arrival timing. 
•  How to structure pregame warmups around skill feel, physical readiness, movement prep, and contact. 
•  Why players need some level of game-like physicality before tip-off, especially bigs and contact-heavy roles. 
•  How physiology, breathing, CO2 tolerance, and arousal levels connect to focus, decision-making, and emotional regulation.

UT Martin Head Coach Jeremy Shulman joins the Slappin’ Glass podcast for a deep dive into building a defensive system around conviction, trade-offs, and player fit.

Shulman discusses the philosophy behind his unique defensive approach, including why his teams lean toward containment, switch heavily, borrow matchup-zone principles without playing zone, and still find ways to generate turnovers without relying on full-court pressure. He also details how he thinks about solving mismatches after switches, layering post coverage, recruiting for basketball IQ, and turning rotations and closeouts into a strength.

In the “Start, Sub, or Sit” segment, Shulman breaks down attacking hedge coverage, including flipping the screen, RAM screens, and re-screens, before sharing broader thoughts on pick-and-roll offense, the power of the pass, and studying ideas that genuinely fit who you are as a coach.

What you’ll learn

•  Why defensive identity has to begin with what a coach truly believes in 
•  How Shulman blends man-to-man, switching, and matchup-zone principles 
•  Why switching everything can reduce confusion against slips, ghosts, and misdirection 
•  How UT Martin thinks about post mismatches, doubles, digs, and defensive layers 
•  Why putting two on the ball can create steals without becoming a pressure team 
•  How scouting, film, and player processing shape scramble defense and closeouts 
•  Why trust is the hardest thing to build quickly in the current roster-building era 
•  How agents and NIL have changed the way coaches think about buy-in 
•  The teaching details behind flipping ball screens against hedge coverage 
•  Why Shulman views pick-and-roll as a way to move the ball, not just create downhill scoring

College basketball’s NIL era has quickly become one of the most disruptive forces in the global basketball market.

In this Slappin’ Glass Deep Dive, Eric Fawcett sits down with Kevin Sweeney, college basketball and NBA Draft writer for Sports Illustrated, to unpack what NIL money really looks like inside the modern college game, how schools are building rosters, and why the American college system is now pulling players from Europe and other international markets at a level that is reshaping the sport.

Sweeney breaks down the current NIL spending ranges across college basketball, from Final Four contenders operating with payrolls that can reach $20 million-plus, to mid-major programs using targeted spending to compete for league titles and NCAA Tournament bids. He also explains why international recruiting has become such a major part of roster building, how college programs are evaluating European talent, and where the process still has major blind spots.

The conversation also gets into the uncertainty around NCAA eligibility rules for international players, the sustainability of NIL spending, and why roster evaluation now requires a deeper understanding of translatable skills, role fit, personality, learning style, and reliable intel.

For coaches, scouts, executives, and anyone trying to understand where the basketball talent market is headed, this episode offers a clear look inside one of the most important shifts happening in the game today. 

What You’ll Learn

•  What NIL spending looks like across different levels of college basketball, from Final Four contenders to mid-major programs. 
•  Why European and international players have become such a major target for NCAA programs. 
•  How NIL has changed the global basketball market and put college basketball in direct competition with professional leagues. 
•  Why international recruiting still has major evaluation gaps, especially around player intel, role fit, and translatable skills. 
•  What the NCAA’s recent eligibility guidance could mean for older international players entering college basketball. 
•  Why the best roster builders are looking beyond scoring and placing more value on players who can defend, connect, cut, space, and impact winning without needing the ball.

Scott Wylie, co-founder of S2 Cognition, returns to Slappin’ Glass for a deeper look at how athletes process the game at speed — and how coaches can use that information to better teach, train, and build around their players.

The conversation moves from theory into application: matching systems to cognitive profiles, understanding the trade-off between decision speed and accuracy, and designing practices that help players make better decisions under pressure. Scott also breaks down how stress, fatigue, spatial awareness, distraction control, and improvisation shape performance in real game environments.

In this week’s Start, Sub, or Sit, Scott discusses what elite players do differently: seeing things earlier, processing faster, and controlling impulses and distractions when the game speeds up.

What You’ll Learn

How S2 Cognition evaluates decision-making
Scott explains the nine systems S2 measures, including visual processing, spatial awareness, decision complexity, instinctive learning, impulse control, distraction control, and improvisation.

Why cognitive fit matters
Not every player processes the game the same way. Scott discusses why some players thrive in open, read-based systems while others fit better in more structured environments.

The speed-accuracy trade-off
Playing faster does not automatically mean playing better. Scott explains how coaches can help players toggle between speed and control.

How pressure changes processing
The conversation explores how fatigue, stress, anxiety, and game environment can affect a player’s decision-making.

Why spatial awareness matters
Scott and Dan discuss how spatial awareness can influence shot selection, positioning, passing windows, and a player’s sense of being open.

How to train adaptability
Scott introduces “VEX drills” — practice designs that violate expectations and force players to adapt when the normal solution disappears.

What separates elite players
The best players are not simply faster reactors. They anticipate earlier, control impulses, block out distractions, and stay flexible in chaos.
