Michigan landed a major offseason score Thursday when former USC running back Ty Isaac announced his plans to become a Wolverine, beginning this season.

The 6-foot-3, 225-pound Isaac is a former five-star recruit, was considered a top-30 player in the 2013 class and was a player Michigan nearly received a pledge from two years ago.

Most believe Isaac's combination of size and speed will pay dividends for Brady Hoke and Michigan. But one question remains.

When?

Isaac is transferring to Michigan and is reportedly seeking a hardship waiver from the NCAA for immediate eligibility next season.

Part of the reason for Isaac's transfer from USC was to be closer to his mother in Shorewood, Ill. Isaac's mother is reportedly dealing with complications from surgery to correct hearing loss, and that surgery prevents her from flying.

Isaac also opted to transfer to Michigan, which is a little more than 250 miles (about a four-hour car ride) from his hometown.

So, does he have a case with the NCAA to gain instant eligibility?

While the situation seems to have some grey areas, Isaac's quest to gain instant eligibility from the NCAA might come down to how serious his mother's condition is.

And then there's the 100-mile issue.

"(The family health issue) has to be a debilitating injury," said John Infante, a former NCAA compliance officer who operates the popular "Bylaw Blog" for AthNet. "It doesn't have to be life-threatening, necessarily, but it would have to be something that prevented her from working or getting around, if it's a surgery for hearing loss, I'm not sure if that'll qualify, but it might.

"His bigger problem, though, is that you're required to transfer within 100 miles of the family member. Being four hours away or 200 miles probably isn't going to cut it. There are considerations that can trump that, one thing they say is that if you're dealing with someone suffering from such a serious illness that they've been given a defined amount of time left to live, then all other considerations are off the table. But in this case, it doesn't sound like that's the case."
