It wasn't last season. It was two seasons ago. However, I would imagine there are still plenty of players on the team who went through the process.
I found out because I was talking to a coach who personally knew Chad Gilson. Rumors recently came out of the Hawkeyes camp that Gilson has been impressing. This coach confirmed to me that Gilson is now running with the 2's at Iowa and he's only been with the team a year since transferring in from UNI. He went on to tell me about what happened at UNI. He said that it was obvious to all of the Panther players and coaches that Farley's son should not have been the starter. He also acknowledged that Farley's son went on to have a great season last year, but that doesn't change what happened. A DC and at least one LB coach resigned at UNI because of it, and according to him Farley lost the locker room. Obviously, he has probably earned it back. However, things like that can tend to linger.
