Florida Gators quarterback Tim Tebow working on smoother, quicker passing motion

GAINESVILLE — After three years, two national titles and a Heisman Trophy, Tim Tebow still gets questions about his throwing motion.
Spectators of Florida’s spring practices seem to freeze when Tebow reaches back during spring practice, squinting to detect the slightest difference in an arm that’s been evaluated in biomechanics labs and lambasted by pro scouts.
Tebow’s moxie as a quarterback has been certified since he stepped on campus in 2005, but his mechanics are once again being tweaked for long-term effectiveness — and possibly a long-term NFL investment.
