As far as I can tell, Tebow is either a born-again Christian or an Evangelical Christian. People like him wear their Christianity on their sleeves; they always talk about their Lord & Savior, Jesus Christ. Good for them! Would I like it better if Tebow didn't start every interview with that? Sure, but that's the way he is. I could think of a lot worse things he could talk about or a lot worse ways he could be living his life.
Eventually, being a good athlete, he'll probably become a RB something like Frank Gifford; everytime he gets the ball, you'd not be sure he's running or passing.
