Well, I like the move for Trotter. He has been on the team for several years running Malzahns offense. Also, he has the seniority of an older player to be a leader for the larger group of younger guys.
Also, with the re-work of the OL, there will be some new names to listen for. One is Christian Westerman. Reports are that he has a serious mean streak and has gotten in fights with pretty much every one of the DL.
