Also remember the Jets were horrible at getting to the QB the last 3 years. They were so bad they brought in Mayhem. Going back to his Baltimore days, I think the thing that makes this defense effective is being thick in the middle and having that 1 Bryce Paup style swing guy who can pressure the edge.
Personnel-wise, the Bills have questions at NT, OLB, OLB, ILB, and ILB. I'd sit on the 3 CBs they drafted high and see how good they are at press/man. They have too many needs to take another CB.
