I read the twitter thread. On D1baseball, there is an article that proposes having roster limits in the fall as well as the spring. I couldn't read it because I don't subscribe, but that seems like an easy way that the NCAA could put a bit more control on the situation. If a coach has recruited properly, he shouldn't need to have 45 players in the fall competing to be one of the 35; he should be able have faith that out of his 35 recruits he will have the 20 he needs to play.
Of course, that wouldn't stop them cutting players in August. But it might make coaches and families think a bit more about who is going to be there at the start of the fall.
