Polian built this team just good enough to win 1 super bowl, and then he stopped caring. Stopped trying to improve. Stopped spending during the offseason, stopped searching for strong draft choices. He tried to ride Peyton's coat tails to a couple more super bowls without having to do anything himself. He hasn't made a single good decision since before 2006.
Maybe the Austin Collie pick...maybe. However, I think Austin and Peyton deserve more credit for making that work.
