Michigan had two high profile players transfer to Iowa in the off season. Cade was injured and lost his starting job to JJ and Erick All who also was having injury troubles and had grown frustrated with Michigan's medical team, got private surgery, and also headed to Iowa.
A couple weeks ago, Cade went down with an ACL injury and it was announced yesterday All suffered the same injury against Wisconsin on Saturday. I would assume both will be back next season to fight for the Hawkeyes again. Remember when Iowa continued to lose every RB that was on the roster?
