I'm not saying Mack isn't a prospect; I am saying that this statement means almost nothing, unless you tell me you seen extensive tape of him besides last weekend's game (and one or two others).
I don't have a problem with the small school LBers. see London Fletcher for one. Maybe he'll be a target in rounds two - three (compensatory). I just don't see the Steelers risking a first on a small school guy. You know how tomlin likes his "level of competition" criteria for a draft pick.
Seem to recall the Steelers drafting one of the greatest LBs to ever play the game from a small school way back when in the 2nd round. The professionals had this to say about him: "too small to be a pro football linebacker". The guy went on to 9 straight Pro Bowls and the Hall of Fame.
