My bet would be the Bengals. The possible return of Carson Palmer storyline is way too juicy.
A Denver AFC title game rematch would be another likely game - especially if TO is on the Broncos.
Steelers home opponents
1) Kansas City will draw the biggest game. KC once they sign Sam Madison and draft Brodrick Bunkley will look like the #1 team in the NFL on paper. And they'll be playing with a chip on their shoulder to win a Super Bowl with Herm Edwards and barely missing the playoffs last year.2) Denver is likely to be sporting either Ricky Williams or Terrell Owens. AFC Championship rematch game as will add more to the hype.
3) Tampa Bay would be an awesome game, if for no other reason than I'm in Tampa, and they seem to always make for memorable prime time games (@PHI in '03, v.IND in '03, v.Rams in '00 off the top of my head). This would be a great game, but probably not the best option.
4) Miami might be pretty scary next season, but they still would need at least a few weeks to really get people to buy into it.
5) Cincinnati likely won't have Carson Palmer back. At best, let's say it's a coin flip by mid-Summer... if he's not in, and Kitna's gone to Detroit, what do they have to hype this game? It'll be an ###-pounding.
6)Too many people are convinced Baltimore is terrible. Even though they really just had some bad luck last season, I highly doubt they'll be able to market a team that just likes to sit on the ball and strut its defense.
7)Cleveland would probably make for a pretty decent game, but at this point in the season, it just wouldn't be a fair fight. It's hard to market a team that hasn't had a winning record in more than 3 seasons.
8)New Orleans is out of the question. They'll won't hit the .500 mark until week 1 of the 2007 season.
Of those, I think based on what Kansas City does early in the offseason will determine whether they get this game.
