While Shelton Mitchell's departure from the basketball program does leave Vanderbilt with a scholarship to give for the 2015-16 basketball season, we're going to go ahead and guess that Kevin Stallings is done recruiting in this class. He'll probably just give that last scholarship to Carter Josephs again, and have it available to give next year.
Here's a visual breakdown of Vanderbilt's basketball scholarships and the year that the player is expected to depart. Obviously some of them will depart before that (and some may redshirt and end up departing later than projected), but thanks to our administration's scholarship rules Stallings isn't allowed to over-recruit to account for potential departures:
As you can see, Vanderbilt projects to have two scholarships available to give in the fall.
