Simmons has gone from a liability to a cancer. I get the feeling that the O-Line has to account for Simmons' gaffes on occasion, therefore making them look silly as a unit. Simmons is a bust. A first-rounder, and has yet to reach All-Pro status. Instead, the best Steelers can hope for out of this guy is an average performance.
Simmons, like Starks, is a backup and not a starter. He's too damn soft and gets destroyed by the more competant to average DT's. The Front Office dropped the ball on his re-signing.
