One thing that worries me about Cody Green is where he is keeping his head at right now.
I work at Walgreens here in Lincoln part time in the photo lab while I'm going to school. I can't tell you how many times I have seen Cody Green pop up in a bunch of different pictures, from many different girls, at many different parties. I work at the second closest-to-campus Walgreens, so I get a lot of student pictures.
I'm not saying the kid can't have fun nor that he can't live a little, but he has a full ride to Nebraska to play quarterback. He's been kind of the "hot new thing" on campus with a lot of people (especially girls) following his coat tails. I get the impression that he isn't 100% committed to school and football.
Then on the flip side, you have a guy like Martinez, who is really quiet and reserved. And, from many reports we have seen, he has been doing exceedingly well this off season. It seems to be coming down to a "who wants it more" factor.
