Sounds like it had to do with his parents… Lengthy article here from 247 but the highlights on Michigan:
Many people thought Michigan was high on your list. Is there a reason you dropped them?I mean Michigan was a great school. It was close to home. But when it came down to it my parents didn’t have as good of a relationship with them as they did with the other 6 schools.
Do different schools have different approaches with you?
They’re all pretty much the same. They keep in contact and come to the games a lot. One thing Michigan didn’t do is I don’t think they called my parents as much as the other schools.Is that a big factor for you?
Oh, yes. My parents are a big factor in my decision.
