That depends on how we count. The Scholarship Grid is here.

We are allowed 13 scholarships next year. At the moment, all thirteen have committed players. If Hutcherson returns from a medical redshirt and Grandison decides to be a "super senior", then we will have fifteen players in thirteen slots. "Super seniors" such as Trent and DMW do not count against the limit this year, but they will count in future years.
If Grandy and Hutch leave, and Kofi goes pro, we will have one opening for next year. If more players leave for any reason, we will have more openings. Who else is going to leave? Well, every year I convince myself that everyone loves Illinois and no one is going to leave. I have been wrong every single season so far. In my defense, I will say that I twice predicted Kofi's return, so I don't always get everything wrong.
So, depending on how we count, we could be over-committed by two, or we could have 1 to 4 or thereabouts left to give. We all know BU knows how to count, and we also know that even BU can be surprised. I don't think even BU foresaw Adam Miller's departure.
