I cannot remember the last time a team got smacked down as badly as Pittsburgh did last week, only to come back a 14.5 favorite the following week.
14.5 = (9/11/11 expectations - 9/11/11 outcomes) * (Steelers talent - Seahawks talent)
In other words, you piss of a good team, give them home field, and bring in a team with no QB, there's gonna be a beatdown. Now, I don't know about 14.5. Could be 10, could be 30. But it ain't gonna be pretty.
