This is a VHS tape. The Mountaineers finished the 2001 season ranked 104th in NCAA Division I rushing defense . in 2002, they implemented the 3-3 Odd Stack Defense and finished the year ranked 11th in rushing defense! The 3-3 Stack is a rush-oriented defense that is simple to run, gives your defense more second level players (making it easier to see and get to the ball), the odd-man front confuses offenses and creates problems for blocking schemes and it's great for teams with smaller personnel on defense. Casteel and Kirelawich give you everything you need to start running the 3-3 Stack: personnel suggestions, alignments, responsibilities, and techniques. They present all of the principles of the defense with detailed diagrams and practice footage. An excellent defensive overview. Used VHS in excellent condition
