Here's classic ICE for you. The thread is started by saying "let's just let Bledsoe finish out the year." Nick clearly even says "Don't mistake what i'm saying. JP is the starter next year." Now, after having been shown situations where a guy has started after a year on the bench, your argument slides from "every game he sits we get a game further away from the super bowl" to "he has to play next year," which is not an argument against the original post, but a backtrack because he has been given counter-evidence (Tom Brady). I've read the posts from the guy who started the thread and he says wait on starting Losman until next year, you said no to that, and feel now that you are arguing against him even though he is in agreement.
I still say he can't leapfrog from #3 to #1. If the coaches don't have enough confidence in his play that they feel he is the best person to go in if the starting QB is injured, then starting him will do him (and the team) no good, and could do him harm. And remember too that he has lost a half-season of off-field development...
