Last year: I did not rank Isaac, who was on the USC football team. He ran 40 times for 236 yards and 2 touchdowns, and he caught 4 passes for 57 yards.
I was a pretty big fan of Isaac coming out of high school, but he went to the dastardly USC Trojans instead of the local-ish favorites like Notre Dame and Michigan. Lane Kiffin (and his replacement, Leatherhead from TMNT) gave him the fifth-most carries on the team, so he was not particularly irreplaceable. However, he did average 5.9 yards/carry and had some nice looking runs on the chances he did have. In the offseason, his mother had ear surgery that would have prevented her from flying to see his games in southern California, so that was the reason (or at least the excuse) for him to seek a transfer. His options came down to Illinois, Northwestern, Notre Dame, and Michigan, and the Wolverines won that battle.
It's unclear whether Isaac will be available for the 2014 season; he will have to get a waiver from the NCAA, which they are not likely to grant since Michigan is outside the 100-mile radius from Joliet, IL. I went ahead and ranked Isaac on the list, and you may notice that he's the top back in the stable. In my opinion, he's better than anyone Michigan had on the roster prior to last year, and he was better than either Derrick Green or De'Veon Smith in the 2013 class. Isaac is a big body with some nifty feet, decent speed, and an ability to catch the ball. He probably won't play a down in 2014, so Michigan will be without its 19th-most valuable player this year.
