ANN ARBOR, Mich. (AP) - Running back Ty Isaac is transferring from Southern California to Michigan. Wolverines coach Brady Hoke says it was important for Isaac to move back to the Midwest to be closer to his mother and his family. Isaac is from Shorewood, Illinois. Isaac appeared in all 14 games for the Trojans in the 2013 season, rushing for 236 yards on 40 carries with two touchdowns. He finished his high school career at Joliet Catholic Academy in Illinois with a school-record 5,305 yards rushing.
