Wow it appears the stress of coaching a failing team in the SEC could be wearing on Biels.
In regards to Derby, I don't feel right saying anything other than good for him. I can't blame the kid for wanting to give QB his best shot. In hindsight, it appears the Iowa coaches were correct all along in trying to get him to switch positions, and AJ was apparently very stubborn about it. However, he's finally decided to make the switch to TE and most people who are familiar with Derby know that he's a hell of an athlete who has great size. I imagine everything Biels says is true, and I hope AJ goes out and plays as well as he's practicing. It's unfortunate that it took him this long to make the switch, but if he has a solid year he could absolutely earn himself an opportunity at the next level. The tough thing for him will be getting the opportunity to show what he can do. If Arkansas is as bad as they are predicted to be it could be tough for him to showcase his talents given that they will be playing in the most difficult conference in college football.
Looking back at Biels years in Wisconsin I'm trying think about his use of the TE position. Lance Kendricks, Jacob Pedersen, and Jake Byrne are all guys who had solid careers. If Derby is as good as Biels is claiming I imagine he'll try to carve him out a role somehow.
