If there's one thing we know about Tim Tebow, it's that he will do what he wants to do no matter what anyone else says. If he wants to play football again just to prove the haters wrong, he'll do it.
But I don't think the culture that Garcia and Johnson are putting in is that great of a fit for the kind of guy Tebow is. McMahon's original (2020) vision would've been great for Tebow, who's always had that All-American Boy appeal.
