You Gotta Help Me - Why Isn't Teddy Our Starting QB after Brees?

Teddy is a good QB probably would get the Saints to the Playoffs a few times if he were to become the next franchise QB. I don't however see him having much success in the playoffs. He isn't a Q.B that can put on offense on his back. He won't lose you a game but I don't see him winning many either. Against that Minny Defense Bridgewater would of gotten killed.
