The whole situation is odd and I am betting it has to do with the suspension he had previously. Essentially, he was "playing nice" and they didn't, so the gloves came off.
Either way, not a good look for New Mexico.
As clarification, Davie was suspended in Feb 2018 over allegations that he physically assaulted players, obstructed a rape investigation and frequently engaged in racist comments.
In a statement at the time, UNM interim president Chaouki Abdallah revealed that the school’s concerns about Davie trace back to spring 2017. UNM’s Office of Equal Opportunity (OEO) heard accounts shared by graduating football players that depicted abusive practices in the football program. The OEO then launched an investigation. Two separate investigations reached the same basic conclusion: A number of witnesses portray Davie as bigoted, obstructionist and reckless with player health, but some of those allegations either lacked corroborating evidence or were contradicted by other accounts.
What contributed to Davie's dismissal after these investigations' results of player abuse was probably the suicide of Nahje Flowers, 21, who had been dealing with mental health issues and thoughts of suicide when he was prescribed antidepressants by a school psychiatrist and was instructed to sit out for at least two games. The doctor who examined Flowers was concerned enough to say he shouldn't play but that was overruled by coaching staff. Davie was fired three weeks after Flowers committed suicide with a gun in his dorm room.
His brain at autopsy showed CTE. The family filed a lawsuit yesterday against the school, Davie and the NCAA.
