I think the easiest option is to give the Sr’s that want it another year and don’t make their scholarships count against the total. Not all of them will take the offer so it wouldn’t be the full class anyway, many will just opt to move on with life.
Bit there are costs for the extra year for those who do stay and of course it would surely affect playing time and opportunities for those younger classes who would have started to get playing time next season when those srs had graduated but now won’t because they’re still there.
But to me that is the easiest solution to at least solve the scholarship issue and still allow a full signing class.
