The questions is though who would be better for the Bills this year, Tebow or Nasty Nate? Is this really a question? A guy with some success as an NFL QB with almost a 2-1 TD/Int ratio (17 TDs 9 Ints) or historically bad Nasty Nate (1-4 2 TD 8 Ints)? We could sign Tebow tomorrow and start him on Sunday and he would be better than Nasty Nate.
Denver won a lot of those games due to late game heroics by Tebow. He may not be the best QB in the world, but he is a winner. I can particularly remember the game vs the Rex Jets. Denver had the ball down by 5 or something and they knew what he was going to do but he still beat them.
I'd take that at this point.
