This has everything to do with the playcalling and almost nothing to do with what Tebow can do. Fox and McCoy suck, they run the ball on 3rd and long time and time again, and don't even give the kid a chance to win it.
And also, if Matt Willis cathes a ball that hits him in his damn hands, that last drive would have look a lot different too. Tim has Pee Wee level coaches and high school level wide outs. How can you expect him to be any good?
