I have said it on several past posts about Tebow, he is not, and never will be, an NFL QB. He just plain sucks at it. While it is true that he trained very hard to correct his goofy throwing motion and lousy footwork, what hasnt been corrected, and more than likely never be corrected, is his inability to read defenses and coverages. When he was here in Donkey Town, they had to rewrite and simplify their playbook just for him. As for the "winning record" that he had in Denver, that was a pure fluke. He can only play college style football. Most of the teams they played that year had not faced a college style offense since, well, college. But look at when they played Detroit, Green Bay, and New England. Those teams all watched video and prepared themselves to play a college style offense. When they did play, they demolished Tebow and the Broncos. That play off win against the Steelers, was nothing more than the Steelers looking past the Broncos and being unprepared. They were losing badly at half time. The second half, they came out and got their heads on and back in the game and took it to OT. The opening play of OT caught Denver in an illegal formation that the Steelers saw and hesitated, expecting the refs to throw a flag. They never did and the hesitation allowed the receiver to get a jump on the defender and the rest is history. One thing all the Tebow lovers fail to see is that there are 10 other players on the offense with him. It is NOT Tebow, but ALL the other players who contribute to make the offense work. With a good supporting cast, a mediocre QB will look better than he really is.
As far as Tebow correcting his throwing motion, that remains to be seen. If he ever gets a chance to play in a game. It is one thing to work out on a practice field, and something entirely different to do it full speed in a game situation. My feeling is, if given the chance to play, when he is under pressure from some of these DBs, he will revert to what he knows and does best, throw with that same goofy motion and footwork. If Tebow wants to play in the NFL, he simply needs to swallow his ego and over-inflated pride, and play a position, like running back, that he actually has some talent for.
