At this stage in the game he's in no position to hold out for what he wants. Take what you can get, or you're out of the game. If by a miracle some team takes you as a QB, it's only going to be a backup position and you're gonna be riding the pine 95% of the time.
Meanwhile, has there ever been any fullbacks who could throw a surprise pass here and there? (I know, every throw with Tebow is a surprise...)
