Let's just look at his record as a starter. Tim Tebow is 8-6 as a starter. That includes 7-4 as a Bronco, but he lost the last three regular season games he started, obviously they figured out how to stop him. He did win a playoff game, with a dreadful 47.6 completion percentage, and he lost the following game with a absolutely horrendous 34.6 completion percentage.
Let's compare him to a good quarterback, who happened to play with the same personnel. Peyton Manning is 12-3 this year. His worst completion percentage of the year is 50%.
Tebow took a very good Denver team and played very mediocre. He's a quitter, he's a spoiled, entitled, overrated crybaby. He gets extra credit because of how he acts in front of cameras, even though he clearly has trouble putting a sentence together. I do not get the Tebow worship and I can't help but think it has to do more with his professed faith, than his actions.
