Check my math, but I believe there are 84 players on scholarship. 10 players exhaust eligibility this year assuming both Hayes an Crawford return. If they get the grad transfer, they'll be at 75 before adding any recruits.
I expect 1 or 2 grad transfers, and there are always a few transfers for guys who have bee passed up. However, it's going to be close getting down to 85.
...having said that, it typically seems to work.
He has announced that he will not be applying for a sixth year of eligibility
