Tim Tebow took snaps and threw passes as the three-day minicamp for rookies got under way. "Oh, it's great because we can go back and watch it," said the ever-excitable Tebow following the 90-minute workout on a chilly morning. "We can look at every play, every throw, go back and see what I did good, what I did bad, what I have to work on and what I need to change." Some scouts think it could take two years for Tebow to make the transition from combination college quarterback to prototypical pocket passer -- if he ever does. Others argue his success in college, his passion for football and his work ethic will make the transition smoother and shorter. Broncos coach Josh McDaniels, who made waves when he traded three draft picks to Baltimore to take Tebow with the 25th selection in last week's NFL draft, said it's unrealistic to put a timetable on Tebow's transition. McDaniels has dismissed the notion of moving Tebow to H-back to start his pro career. And with Kyle Orton, Brady Quinn and maybe even Tom Brandstater ahead of him on the depth chart, many expect Tebow's contributions as a rookie will come in wildcat formations.
