The Steelers are listed as about seven-point favorites against the Browns. I'd probably take the over, given that the Browns have little left to play for and they'll be starting Seneca Wallace at quarterback. Ben Roethlisberger's role in this one could turn out to be crucial. He was a full participant in practice Thursday.
The Ravens, meanwhile, are listed as anything from even money to three-point favorites against the Bengals. I can't disagree that Baltimore should be the favorite, but this will be a key game for Steelers fans - the Bengals are a talented team with a lot on the line. If the Steelers win and the Ravens lose, the Steelers would get a first-round bye.
The Patriots are between 10- and 13-point favorites against the Bills. If the Patriots and Ravens both lose and the Steelers win, the Steelers would receive a bye and home-field advantage throughout the playoffs.
