Coach Colin Lark, defensive backs coach at Bishop Lynch High School in Dallas, Texas, joins the Board Drill to teach Stump coverage from the ground up. Stump is the three by one check out of the cover seven world: a four over three concept that matches any three receiver surface while keeping split safety structure intact.Coach Lark walks through every position rule, from the corner's mod technique and the in/smash call to the nickel reading three to two, the safety's vertical rules, and the three by four push mechanism. Then Kyle and Matt stress test the coverage against real trips concepts from Notre Dame's offense, dig into formation checks against attached tight ends, sniffers, and bunch, and break down spring film including a pick six against stick.If you run Stubbie, mini, or special and you're tired of getting beat by the double in from three, this episode is the answer.Coach Lark also demos Football U, his interactive playbook tool that lets players rep out coverage checks from their phones.Check out Football U here: https://www.footballu.comTIMESTAMPS00:00 Intro and welcoming Coach Colin Lark02:09 Stump coverage overview: the four over three check for trips09:20 Stump vs Stubbie: what changes at the corner and why you need both16:16 Why Stump became a red zone answer against the double in22:02 Stress testing Stump against Notre Dame's dagger and sail concepts28:06 Formation checks: attached tight ends, sniffers, and bunch33:36 Backside coverage options and game planning around their best player38:44 Spring film: the three by four push, carrying the wheel, and a pick six42:46 Taking three through and handling the dirty over route49:15 Up calls and teaching defenders when to fall off55:42 Final question: the most unique thing Bishop Lynch doesThis episode is sponsored by Sideline HQ.
