In what may be an ACC first - no, wait, there's Makhtar Ndjaiye - Michael Gbinije will start his ACC career at one school and finish it at another: he'll be transferring to Syracuse and so will eventually return to Cameron. That should be interesting.
Ndjaiye of course went to Michigan first, so it wasn't a straight transfer. Pierre Jordan spent his fifth year at Georgia Tech this past season after graduating from FSU. But three in fifty years? It's exceedingly rare.
