In this episode of The Board Drill Podcast, Kyle sits down with Coach Clayton Cason, Defensive Coordinator at Mandarin High School, to talk all things defensive line play. Coach Cason dives deep into his core teaching progressions, how he builds violence into strike technique, and how Mandarin teaches their D-linemen to dominate one-on-one matchups. From laws of D-line play to dealing with double teams and striking like Simba, this is a clinic episode you’ll want to take notes on!
