Cornerback Anthony Standifer will visit Michigan on Wednesday, according to a story from 247Sports. This could potentially result in another commitment.
Nowadays recruits actively follow the recruiting classes of schools they are interested in. Standifer will know full well that UM has 2 DB commits, and he'll probably also know that UM is the favorite to land Wayne Morgan on Thursday. This could very well lead to Standifer committing early, even with all the new offers he's received lately.
His parents are also apparently coming with him on the visit, and that's always a positive, especially at a University as academically strong as Michigan.
UPDATE: A poster in the comments section below has informed me that Standifer will be visiting Notre Dame on Thursday, which suggests a commitment probably won't happen on his Michigan trip.
