Possibly the biggest surprise so far this season is the Tampa Bay Buccaneers 2-0 start. Granted the Buccaneers have not played the toughest competition to this point, but it's never easy to get a win in the NFL.
With the return of a healthy Troy Polamalu, the Steelers defense looks like it is back to its Super Bowl winning form.
Last week the Steelers were virtually able to shut down the league's best running back, Chris Johnson, holding him to 34 yards.
As surprising as it is for Tampa to be 2-0 at this point, I would be completely shocked to see them come out of this weekend at 3-0, look for the Steelers defense to lead them to a perfect 3-0 record.
