Per a Detroit News article, Michigan has offered 2014 Justin Tillman, a 6'7" (per Rivals) PF out of Detroit Pershing (may be a bit taller now per the article). Rivals doesn't list any offers, only interest from Xavier. 247 lists offers from Oakland, Indiana St, BGSU, and Detroit, and interest from a handful of other, higher ranked schools.
Not sure I believe that this is a committable offer, but it'll be interesting to see how this plays out. I assume he's visited, a Beilein pre-requisite to an offer, since he's from Detroit but I'm not sure I believe they're ready to move on from Vince Edwards and/or Trevon Bluiett yet.
