I don't think Tebow is the answer by himself, because there are times when any QB in the NFL is gonna have to throw, and Tebow just can't do that very well (Vick can). But having a good O-line oriented to running the ball isn't something that would only benefit Tebow. So I don't know if it is a case of having to build a team up around Tebow to fit his style of offense.
And he's proven in the last few games that he can move against NFL defenses. I think his size, instincts, and willpower are what make him a more special player than others who have tried to do the Wildcat previously. Of course, the NFL is not the same as college football, but his style consistently worked against teams prepared for it because he was so good at it. It takes more than just size to succeed in that role.
The O line just a part of the puzzle. You need the right type of receivers, less TE more RBs on depth chart ect... That doesnt fit the conventional NFL offense.
He is tough to prepare for but as they get more tape he will get easier and easier to prepare for. He got a Jets team who had 3 days to prepare and then put up a TOTAL of 229 yards, 95 of which came on final drive and some of the Defense call they made in the final drive were questionable when what they did the whole game had been working and they went away from that.
I just dont see any way unless he magically learns to throw how they can continue to succeed long term. To me its just like the Wildcat, its fun gimmick that will only work for so long in the NFL.
