I'm not going to make any guarantees, but I would be very surprised if he ends up being a linebacker. He's a big boy already and it doesn't look like he has the speed to play LB at the B10 level. Definitely like his potential with his hand in the dirt though.
Here's the thing... I know this isn't Earth shattering news or anything but when it comes to Iowa recruits I stopped looking at stars a long time ago. The best players on the Hawkeyes teams usually end up consisting of about half of them who were pretty highly recruited and half of them who were unheralded diamonds in the rough.
Just look at the current team for proof. Fairly highly recruited... Rudock, Hamilton, Carl Davis, Walsh, scherff, etc. Unheralded recruits... Lowdermilk, Trinca-Pasat, D. King, Weisman, Duzey, Jewell, Bower, etc.
The point is it's always a mixture of the two that end up making Iowa a good team. It all comes down to development. Just an FYI to the DBs out there who like to enter recruit threads and whine about lack of offers.
