Why Did The Steelers Win SuperBowl Last Year...And What Happened?

Bettis is gone. Never underestimate the importance of even two to three plays a game, third down conversions etc....and leadership. Ben is a good qb, but Bettis was thier leader. The team played last year to retire Bettis with a ring.....and he helped them do it. This year the O line is lacking that pop, and the defense is good while not spectacular. I hate to say it.....it's like the steelers had one of thier "boys" removed.
