Heading over the Mid Season Hump...Who on the Bench Will Step Up in the 2nd Half??

So far we've seen DWYER step up, COLON is settling into his new position and FOSTER has elevated his game.

But I was thinking Defensively:
-A Run Stuffer on the Line like McClendon
-Who's gonna get to the QB and add some pressure?
-How about someone who can make a few key INTs???
