@nuleafjhawk The heisman has always bugged me because it's usually not the best player in college football, it's the best QB, RB or in some cases the best receiver or rarely defensive player. Pretty sure no defensive lineman or linebacker or offensive lineman or even fullback has won the thing.
It's always interesting to note that when RB's and QB's rack up impressive stats it's only because of the offensive linemen. It's why Ron Dayne remains my favorite college player because after gaining 300 yards or whatever he'd be interviewed and he'd always tell the interviewer to go talk to the offensive linemen because they were the ones who made it possible.
As for Mayfield, I haven't followed OU too closely to know what the issues are with him, but I'll read your link and find out.
