Most likely there's some tongue-in-cheek behind Rex Ryan's proclamation that the Jets should be favorites in the NFL Playoffs. He can't REALLY believe that. He can say he believes it, but deep down, that can't be the case.
That being said, we're not sure why people would get mad or flip out. Dude is trying to pump up his team, and it probably worked. Who cares if the Bengals use it as billboard material. If they need that to get psyched for a game, they're in trouble.
