Tebow can win games and sell a lot of tickets, yet everyone in the NFL seems to hate him.
NFL coaches and offensive coordinators seem convinced that he actually does not have the skill to win games and that his performance in Denver was an unrepeatable fluke.
I have not seen one coach or OC criticize his beliefs (although quite a few talking heads, some players and also former players have) - but I have seen several cite his stats as being problematic.
And contemporary sports is, you will agree, obsessed with statistical analysis these days.
