I agree with Matt and Pete. The first two games are very winnable. The Titans coming into Pittsburgh after the towel stomping? They're not going to be able to hear a thing with the crowd going at it all game. Yes, Cutler gives the Bears an outside chance, but he has a TE to throw to and that's about it. I'm not worried about Hester. He can only create separation with straight line speed, and the Steeler's Zone D usually takes those type of plays away.
I would have given the Raven game @ Baltimore to the Ravens if it weren't a Monday night game. The Steelers usually sparkle on the national stage. One game that could trip up the Steelers could be @ San Diego. Merriman coming back should help get their D back on track.
