Adam Schefter, of ESPN, reports Florida QB Tim Tebow has been working on the way he holds a football, shifting it from his waist to his shoulder. He is concentrating on taking three- and five-step drops instead of working out of the shotgun formation he did at Florida. Tebow will not unveil his new delivery at the NFL Scouting Combine, preferring instead to wait for his Pro Day March 17. ‘I’m not changing who I am or how I approach football,’ Tebow said. ‘But there are things that I can get a lot better at. 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.’ Our View: Tebow’s mechanics have been a problem for him throughout his college career. Our very own Cecil Lammey and Matt Waldman were at the Senior Bowl practices in Mobile, and Tebow did improve over the course of three days. His improvement has scouts excited about his development as a passer, and if he looks good at his pro day his draft stock could be on the rise.
