If you don't think that has any bearing on Williams' ability to pick up an NFL offense, especially given he ran a very pro-style system in college, then that's fine. I just disagree. Clay is being asked to go from Tulsa's spread system, where he played multiple positions and was more of a jack of all trades then a true tight end or fullback or running back or receiver, to learning H-back (which basically means he has to learn how to be a fullback and a tight end) in an NFL offense. Learning one position would be a big enough change going from Tulsa to the NFL, but learning two positions is a monstrous change. Much bigger than the change that Williams is being asked to make playing the same position from a college pro style system to an actual pro style system (though, to be fair, Petrino's system is from a different tree than the modified West Coast system they run in Green Bay).
Put this way, Williams got the Mackey Award while being a pro style tight end. He's still a pro style tight end. Guys like Tebow got the Heisman while being a spread style quarterback where he's being asked to play pro style quarterback in the pros. That's why the award has relevance.
