Uhm, Corey Mays and Demorrio Williams have been playing pretty well so far.. They are not pro bowl linebackers, but i'd say specifically those two guys are not the biggest problem on this defense.
Mays didn't have the best game statswise today, but Williams was credited with 9 tackles and 1 assist. Not to shabby aye?
The fact that Rothlisberger won't freakin go down is the problem. Very few linebackers in this league can cover Hines Ward or Heath Miller for very long, certainly not as long as Rothlisberger has to throw..
