Here's the way I see the benefits of Tebow
1. Doesn't turn it over
2. Very few negative plays, always seems to get a yard, throws it away when he needs to
3. Gives the backs an extra second to get to the second level
4. Buys time to let bad receivers get a little more separation (normal QB would not be able to find guys to throw to)
5. Good presense in the huddle
6. Helps the defense, controls the ball, doesn't put them in a short field or in a position of having to take chances
7. Throws well on the run and outside the pocket, also needed with bad O-line and bad receivers
8. "Gimmick" system gives what would otherwise be the worst collection of offensive talent in the league a chance to compete.
Alot of those characteristics describe another team who has had some recent success.
