If he resigned, its a matter of formality. It clearly reads that they were going to have to take action.
Having worked in the aerospace industry for years dealing with the government personnel and ethics laws involving public servants, I clearly understand the intent and ridiculousness of implementation due to language. NCAA rules are bit like that too - I get it.
Its too bad that he is forced out on a trivial rule. It amounts to $2~3/player per incidence. If he did it 10x, then its $20~30/player over time. Given the precedence, he would not have been required to be forced out. Sounds like the school overreacted a bit, if its truly only pizza money as indicated.
At the end of the story, it quotes the following:
"The most famous NCAA infractions case involving pizza came in the early 2000s at Utah with Rick Majerus, the legendary men’s basketball coach who died in 2012. He was accused of paying for players’ meals after practice and during film sessions, constituting impermissible benefits.
Thomas Yeager, the head of the NCAA infractions committee, admitted “these were not five-course meals or steak meals at the finest restaurant in town.” Utah was penalized a basketball scholarship while Majerus was ordered to attend a regional NCAA compliance seminar.
“I guess the only thing I should have done was said, ‘You owe me $9 for the ham and eggs and sausage,’” Majerus said at the time. “I’ve got to think with my head and not with my heart.”
