Maybe they should, once in a blue moon. It is not defined as an Offensive award. As for Manziel, frankly, big numbers against Sam Houston State and South Carolina State just do not impress me. Nor does his arrest record.
I haven’t heard about his arrest record. But that’s a separate issue not pertinent to this question. Two subpar nonconf opponents is to be expected. How many previous Heisman winners played smaller college programs early in the season??
LBs have the butkus award and its a great one. I wouldn’t be against the award going to a Def player or even an O lineman if he clearly was the best player in football. But aside from the “want” to give him the award and his irrelevant “storybook” qualities, his contribution to the team is not equal to Manziel’s for the reasons already given.
