I give Tebow a little more credit than the other poster you quoted, but Broncos/Tebow fans REALLY need to stop with this "if you criticize Tim Tebow it's because you have something against him personally" bull****. Really, guys, it's wearing thin.
I give Tebow a lot of credit for the win against Pittsburgh. Really, I do. But let's be honest for a second here. Had the Steelers played any other QB in the league, do you really think they'd be lining up in Cover-0 and Cover-1 Robber with as many as 9 guys in the box for a good portion of the game? Props to Tebow, when he had a guy beating man coverage deep he got him the ball, but those chances were only there to take because he isn't respected as a passer in the first place. I've never seen a professional quarterback get that little respect in a playoff game, seriously it was astounding.
I think there has been a huge overreaction to the Pittsburgh game. People are hopping on the "see what happens when you let him loose??!!" bandwagon, but I just don't see it. I don't think for a second he'd be more successful in a traditional offense, or if he was allowed to air it out for prolonged period of time. He is a tough kid who has trouble completing a lot of the passes that an NFL quarterback has to make. His best attribute as a passer is throwing an accurate deep ball, and that's how he'll complete the majority of his passes and make his mark passing the football, but in the end, that's a very limited skillset in this day and age.
Tebow is a very nice young man, and I have absolutely nothing against him personally. Actually, I find myself rooting for him a lot, because he's exciting as a player and likeable as a human being. That doesn't mean I can't think he is a below-average quarterback, though.
