with class sizes 30-40 that yields 120-175+ on the roster

5-6+ deep on all of the position slots. There would have to be one hell of a NIL to keep the guys who aren't likely to crack the 2 deep. Maybe, maybe a few elite schools/coaches can convince guys to remain in the "system" for a chance to play for a championship/draft slot senior year. The transfer portal will see a lot of disgruntled players, with fewer options of places to go if most teams have an overstuffed depth chart. FCS and D2/D3 schools might have a harder time getting recruits out of high school, but they might have an avenue for filling out a very competitive roster filled with transfers.
