It's a double-edged sword. You've got a bunch of 18-22 year old kids. Some of whom probably have grown up in less than ideal circumstances, and ALL of whom have had smoke blown up their ass their entire HS lives as coaches have fawned all over them telling them they're amazing and they have started to belleve that their their shit don't stink.
Most of them might benefit from 4 years with a stern hard-ass coach who is going to DEMAND their best--while offering loving support of their efforts to produce it--to actually mold them into the young men they're capable of becoming. Sounds like that's the idea OAM is offering. It's a laudable idea, and frankly what many of our favorite coaches from this sport made their name doing.
Problem is that those coaches are going to increasingly have trouble in this sport. If you can declare for the transfer portal every time some coach is hard on you and hurts your feelings--even if you deserve it; even if it's what you NEED at that time to grow--those coaches are going to have trouble recruiting and keeping a roster intact.
So it's lose-lose at this point. Be nice and you're a pushover; be tough and you've got no roster.
