Look at the New England Patriots a few years back. They were perenial losers for a few years at that point. Two weeks into the season Drew Bledsoe goes down with an injury. They start the season 0-2 under Bledsoe then this unexperienced young kid by the name of Tom Brady steps into the role. Struggles slightly early on, but yet, finds ways to win games. Do they go back to losing with Bledsoe, or do they keep Brady who has a weaker arm, less accuracy, less mobile, etc keep winning. They stick with the young gun who is winning, and it has proven to be the smartest thing in the history of the New England Patriots. Moral of the story.... You stick with who will win games... If M-Dez wins games keep him in.
