According to Sam Webb we might have some possible surprise commits. I would think that recruits most likely would not commit to Michigan unless they visit it first. Here is a list of recruits that visited Michigan and are not early enrolled at other schools.
(DE) Jason Ankrah-Nebraska commit
(OT) Travis Bond- NC commit
(WR) Willie Haulstead- FSU- He recently committed to FSU
(S) Donovan Tate- NC commit
(WR) Jamal Patterson-Stanford
(WR) Travante Stallworth-Auburn- Recently committed to Auburn
(OG) Stan Hasiak- Cal
For some reason I think it could be a UNC guy because they have 3 OT's and 5 safties in their class just this year. But I also heard that Stan Hasiak has some family that lives close to Michigan.
