The problem with that argument is that this still isn't an isolated incident. He has done the same type of thing in 4+ games this year. He has been the definition of inconsistent and that is what fans fear. Some holes can't be dug out of. Most of the time, against playoff caliber teams...especially in the playoffs, teams don't dig out of those holes. So, getting his act together...eventually, is better than never doing it, but it isn't a reliable approach to accept. Stafford has got to find a way to improve what he's doing to start games. I don't think there's any chance they go all the way with how he's played the last 6 games.
