Barwin is a threat as a pass rusher; and frankly he's a good all around player who rarely gets hurt. And he brings attitude to a soft defense. He's what you want. House is a #3 CB.
peppers was a better threat as a pass rushed and a better all around player
so again, how does signing barwin and lossing peppers and keeping everything else the same make the defense any better?
we have to fix the main problem, the main problem is our secondary
