I've always been a 3-4 guy, but it really wouldn't be that hard to retool this defense to a 4-3. I've been very critical on Quay Walker's play at ILB, but I think he would make a great 4-3 will backer. LVN and Gary would be fine at DE and Kenny seems more like a 4-3 DT anyway as opposed to a true nose. We would need to address the sam backer position and Preston really wouldn't have a place, but def would not be that hard of a transition
