In a new ESPN article Jadeveon Clowney's high school football coach Bobby Carroll says that, "For some reason (fall of 2008) Clowney expressed a great interest to go to Michigan." The article doesn't go on to say what happened to cool that interest, but that Tony Gibson was recruiting him. I found this to be quite interesting. Link below.
FWIW. Michigan doesn't seem inclined to get re-involved.
