Clarification for the facilities: everything would operate in a tier system from 1-5. Different schools would have different tears for example. A MAC school like Akron would have typically a tier one training facility whereas Ohio State would have a tier 5 facility. Each facility comes with benefits such as tier 1 = +1 speed +1 strength etc. whereas a tier 5 facility would give players + 5 speed +5 strength.
this could be done with an academic building (awareness etc)
speaking of academic buildings, schools with higher prestige in terms of education such as Duke would have a better academic center, but lesser training facilities, locker room etc
Practice facilities, training rooms etc.
With money from the Booster’s/NIL section coaches would then choose where to allocate their funds. You could spend it entirely on your roster or on your coaching staff or spend it on upgrading facilities or you could try to split it between your players and upgrading facilities, better facilities, better recruits, and ultimately better results.
