Florida star quarterback Tim Tebow's NFL prospects are unclear, with scouts rating him anywhere from a first-round pick to a third-rounder. And even then, no one knows whether he'll successfully make the difficult transformation to the NFL.

But give Tebow (pictured hugging his mom) credit: He's addressing the criticism that scouts have pointed his way over his mechanics.

ESPN's Adam Schefter reports Tebow has changed the way he holds the football — moving it from his waist to his shoulder in an effort to hasten his delivery.

"I'm not changing who I am or how I approach football," Tebow told Schefter, "but there are things that I can get a lot better at — my fundamentals. I've never been asked to shorten or quicken my release and not have a loop in it. The changes I'm making have gone very well, and it's becoming more and more natural to me." 

Tebow, who had a poor performance at the Senior Bowl and has created plenty of skepticism about his pro prospects, said he'd have made the changes regardless of what happened in Mobile.

"Probably, just because of the quarterback coaches I've been working with," he said. "I want to get better. I want to be around people who will push me. Without hearing the criticism, I would have done it. It's made me more confident, more accurate. And that's not to say I haven't had this type of coaching in the past. I just have had different coaching than this NFL style." 

Among the coaches he has consulted: former Jets offensive coordinator Zeke Bratkowski, former NFL offensive coordinator Marc Testman, now head coach of the CFL's Montreal Alouettes, Arizona State offensive coordinator Noel Mazzone and former NFL head coach Sam Wyche.
