The history of football is replete with examples of wildly successful college quarterbacks who had little or no success as professionals. It's an entirely different game in the NFL, and Tim Tebow--as great as he was in college--is not an NFL-caliber quarterback. That's the simple truth. No matter how badly he wants it, he will never have a career in the NFL as a quarterback--not in this life. If he were willing to accept that fact and learn another position, he might have a shot at playing. He's a great athlete, and he has the size to be a fullback or tight end. Those are decent possibilities for him. Quarterback is not.
