The scholarship grid is on our recruiting page: http://www.bobcatattack.com/football/recruiting.asp
If you assume that Belack and Noel are no longer on scholarship (they aren't on the roster at OhioBobcats.com) you have:
Juniors this year: 18
Sophomores: 14
RS Freshman: 11
True Freshman: 20
Total: 63
So that would say Ohio has in the neigborhood of 22 scholarships to fill. There could be further attrition and walk-ons put on scholarship that would impact that number. They have 17 commits right now. So I would expect a class in the 22-24 range.
