That is the list of all time 4th quarter comebacks with games played and comebacks. So your logic of "if he didn't stink for 3 quarters" is complete garbage. Either that, or you think every guy on that list is average, because somehow, they got behind in every one of those games. And my guess is that if you looked up the defensive statistics of the teams all those quarterbacks played on during their careers.....Stafford would, by a large margin, have played on teams with the overall WORST defense of the bunch.
Every guy on that list above Stafford is or will be in the HOF.
Any other genius takes about "NEVER" winning games in the 4th quarter?
