I doubt it will ever happen. Tebow is just not that good of a player - although he has won more playoff games than Sam Bradford and just as many Heismans.
Oh, and he beat Bradford head-to-head for a national title.
While I realize none of that matters in the NFL, it still seems to me you can't have it both ways. Why does Bradford, who has been awful, get traded for and Tebow can't even get a shot to try out? You can argue Bradford's mechanics are better all you wish but......when you look at that triumvirate of Bradford, McCoy, and Tebow - none of whom set the world on fire - Tebow (and I'll admit I'm shocked) has had the most successful NFL career of the three.
And this isn't some insane anti-Christian thing with me any more than Michael Sam is not in the NFL now because of his particular issue. They just aren't NFL level football players, that's all.
And it really ought to be that simple.
