Zach Betz joins Matt Waldman's RSP Cast for a discussion about the Air Raid scheme, the Cardinals offense, and Kliff Kingsbury.  

Betz (@alltwentytwo on Twitter) has spent a lot of time studying two schemes: Sean McVay's outside zone scheme in L.A. and variations of the Air Raid used by Hal Mumme, Mike Leach, and Kliff Kingsbury. With Kingsbury's arrival in Arizona, I invited Betz to share his thoughts on Kingsbury's version of the Air Raid, his coaching prowess, and the outlook for the Arizona Cardinals offense.

Topics:

* The Air Raid isn't new to the NFL.

* Kingsbury's creativity with formations and personnel usage sets him apart.

* Why "playground ball" is a good thing.

* Should we be concerned about the Cardinals offensive line?

* Thoughts on Hakeem Butler and Andy Isabella's futures in this offense.

* Why David Johnson should see an offensive resurgence.

* Kingsbury's weaknesses as a coach.

* An extended conversation on coaching and management.
