The NCAA didn’t step in when a player died of heat stroke at Maryland in 2018 with accusations of a toxic culture and unsafe practices.
It was somewhat similar to NW, where the university did an investigation, suspended Durkin for awhile and then reinstated him, causing an uproar with some players walking out in protest. They then fired him the day after announcing he was reinstated.
The NCAA hasn’t had effective rules enforcement for a couple decades, but even when it did, it was monitoring whether schools bought recruits a pizza or a pair of sneakers, and not whether schools were mistreating their players.
