No they wouldn't....
He is what makes the Pats 'potentially' favorites to win the AFC. But if he went to the Cowboys/Colts, who in their right mind wouldn't say they were the favorites to win the Super Bowl? I don't care about likelihood, were just speaking hypothetically, and hypothetically if Moss went to either of those teams, they would be better than the 07 Pats and definitely better than the 08 Pats if Moss stays in NE.
