Well, you guys are certainly right about him cuttin' back on the trash talk...all it took was for the Steelers to not only get their asses handed to them in the game in question, but him being personally torched by Tom Brady for several touchdowns in that game.
Google "Smith Steelers". In the approximately 12 pages that appear, at least 2 entries do not refer to his completely moronic attempt at trash talk at the wrong place, at the wrong time, and damn sure against the wrong team. I don't know what his wonderlic score is, but based on what I do know, I'm bettin' he rode short buses in high school.
I think in 1 of the 2 entries not referencing his big mouth, they mentioned that he's in the doghouse with a coach or coaches in Pittsburgh, so he has that going for him, also.
