Not so sure about that, man. This is the arguably the best defense rex has had since '10. It's must also be a bitch to score points once the weather starts to turn in buffalo.
He had one decent season after two relatively unspectacular ones. I would wait to see if he puts together back to back decent seasons before thinking he will amount to more than a role player.
Of course there is, the D&B's in Buffalo is the one they went to the day before they got their butts handed to them 37-14 by the Bills in 2013
