What does Tim Tebow's being dumped by the NY Jets say about devout Christians in sports, if anything?

This isn’t a sports question. More of a societal question. Does being vocally and overtly religious work against you, especially if you are in the public eye?

Tim Tebow was waived (dumped, fired) from the NY Jets football team this morning. He had been with them for a little over a year. He is one of the most (if not the most) overtly Christian players in recent football history, writing references to bible verses on his eye paint, praying during and after football games, usually on camera, etc.

I don’t doubt his sincerity or devoutness at all. But has it worked against him as a professional football player? Did people overlook his lack of professional level talent because of his religious fervency? Was too much expected of him?
