Pmg, what mean by "lavin has to rethink the situation"?
Dunlap did huge majority of the X&O work for this program so its not like you can just replace him with a new Coach.
Lavin will have to make decisions about the way the team plays moving forward and what they are going to focus on in the defensive end. They have lost the guy that was the teacher of their entire defensive philosophy.
Will they stick with the zone as much, what if the new assistant is more of a man to man guy. A lot of things can change very quickly with a new Coach involved....
