Short version-Rick Butler, A prominent youth volleyball coach was accused of sexual assault by six (!) different former players in 1995. His defense (?) was that in at least three cases, the sex was consensual and happened after the players turned 18.
Despite this, MSU volleyball kept recruiting his players and working with him well after these allegations were made public. They played exhibition games at his facility as recently as 2014.
The head volleyball coach at MSU, Cathy George, worked for him in the past. When she was the head coach at WMU, she was talking to one of the players who alleged Butler had abused her hundreds of times. She apparently told her "I'm sorry that this all happened, but I will still have to recruit from him." (Because, you know, winning.)
Their culture really is every bit as bad or worse than anyone could imagine. They SHOULD fire everyone, wait three years, and start over. They WILL...do as little as possible.
