I'm not as down on Tebow as most people. Think a lot of people hate him due to the media. Truth is...yea, he's a sucky passer but he can surprisingly do enough with his legs to compensate for it.(relative to backup QBs)
I doubt I'd want to go back to Davis. Tebow may not be a good option at QB but he finds ways to put the ball in the end-zone(for his team...anticipating pick six joke). Davis just doesn't seem like a NFL caliber QB. Say what you will about Tebow but the guy did enough at QB for his team to win 8 games, go to the playoffs, and win a playoff game. Would he fit in our scheme? I don't think so. Schotty would have to adjust the scheme and I don't see that happening.
