Rhoda. . .he didn't lose his starting job at Cretin. If he didn't start (and I think you're wrong on that), it was because of injury. Ricardo Johnson III never took Rhoda's job. He was a good HS QB. I'm pleasantly surprised he's had some success at the U, I thought he was a D2 guy. But he has a huge arm and he's a smart kid.
I don't know much about many of the QBs on the roster, but I do know about CDH players. RJ3 did not beat Rhoda out for the job, but Kevin Miley did. And Rhoda did not get hurt, he was just bad. Maybe it was something hiniky in his delivery, but he got pulled for reasons other than injury. Maybe the QB coach at the Gophers fixed everything and he'll be great now.
