Because college presidents like to hide behind the cloak of "purity and amateurism" the NCAA provides. I could see the PAC16 being miffed enough about the many, many millions that the NCAA cost them because they were embarrassed that a couple of yahoo sports interns made them look inept. NCAAs 5 year investigation dug up what we alreadfy knew from the yahoo article and that a tennis player made some long distance phone calls. Im sure the PAC wants to get out in front of the Oregon sanctions also. The big 10 I am sure wants to vacate the penalties against penn state and osu that were similiarly heavyhanded. Not that the conferences would blow up the ncaa to lift in-place penalties, but the spectre of the NCAA being able to hand these things out in a Goodellian manner has to bug them more than the cloak of purity makers them comfy. The schools collectively choose the penalties themselves, the NCAA enforces the penalty. The NCAA isn't some power hungry organization that hands out penalties left and right for the hell of it. The schools altogether decide the punishments, idk why some people don't get that. Not sayign the NCAA is 'power hungry' but I think it overplays its charge in the interest of appearing stern on violations to the integrity of college sports, which Im pretty sure everybody has considered a lost cause since the early 80s.
