Mack Brown, a 4 star running back from Lithonia, GA has committed to the Florida Gators. Rated the #7 RB in the nation, Brown had offers from some big programs, including UM.
At one point Michigan was in fairly good shape with Brown, but after the committment of Livonia's Austin White to the Wolverines, it was unlikely that they would add another back to the class.
Speaking of Florida, it looks like FL WR Chris Dunkley could also be heading to the Gators. Speaking after Florida's "Friday Night Lights" camp, where he dominated any corner willing to take up the challenge, Dunkley named the Gators as his leader. Dunkley has an offer from UM on the table, and is listed at a "Medium" interest level.
The 4 star receiver attends Pahokee High School, where Michigan has recently done very well in, securing 2009 prospects Vincent Smith and Brandon Hawthorne as well as Martavious Odoms in 2008. However it looks unlikely that Dunkley will be re-joining his former teammates, since Michigan is pretty loaded with receivers already in the class.
