A lot of those top coaches are evil but filthy rich men. They essentially view their players as slaves. It's no surprise the Alabama Murderers/Tide let Brandon Miller continue playing at the coaches discretion despite Miller texting the other murderer that the gun he's letting him use is in the car with a couple bullets in it. But back to the coaches, they will use any loophole and cheat through acquiring players or paying them off to come to the school. If their grades are bad, strings will be pulled. These greedy pig coaches want all the money for themselves and are probably now jealous of NIL deals becoming a reality. Practically all these top coaches have scandals to their name despite the vast majority of their dirt being covered up through the years. That speaks volumes. But when they're sent packing from school A, school B will gladly take them in for a restart.
As for the basketball itself, it's way better than the nba where players take every second or third night off, rarely play defense and are just present in the games to get their paychecks. These nba players do not give a single damn about the regular season anymore.
