Yeah, hopefully he was good with his money.Legally speaking, yes. His biggest consequences will be financial/professional and personal with his wife and kids.
I honestly don't even know what you do next if you're him.
Assuming the narrative can’t be rewritten to get rid of the knife threats his only hope for coaching again would be if he had some really strong personal relationships with successful head coaches and takes work as an analyst for a few years.
Hard to see how he could ever get a HC opportunity. By the time his reputation could be laundered he’ll probably be too old.
