Coach Lambert is a Boilermaker.
He has some experienced guys coming back that will make an impact in his defense. Being the third defensive coordinator in 3 years is no small task, he has an opportunity with an experienced defense to make some serious strides.
After looking at some past tape of Coach Lambert’s defenses, it looks like he is a 3-3 stack guy by trade, but he has been in a 3-4, 4-2-5, 4-3, 3-5, etc.
To me - he is going to cater his defense around his players and be very multiple - there is no one size fits all - like Bob Diaco wanted to do with his 3-4 defense.
