Metrics bring Tebow up, McCoy down

One of the most intriguing aspects of the draft is seeing how collegiate players who were considered to be equals at that level can suddenly seem to be drastically different talent-wise once the professionals come calling.

For example, over the past couple of years, Sam Bradford, Jimmy Clausen, Colt McCoy and Tim Tebow were all considered to be elite quarterbacks when playing on Saturdays, but their Sunday prospects look to be dramatically different. Bradford is all but certain to be selected as the No. 1 pick in the draft, Clausen is projected to go in the upper half of the first round, and McCoy and Tebow are almost certain not to be taken until the second round at the earliest.
