I think the difference here might be the "injured" party. When KU cheated and got a top recruits before NIL, it was hard to demonstrate who had been injured. Put another way, it was not like ISU was complaining to the NCAA or Big 12.
Here, it is hard to imagine that Ohio State, Penn State, etc will simply stand by and do nothing. Have to imagine there are powerful schools that are going to be severely ticked off and won't stay silent or let Michigan get away with no punishment.
Sure, but like I said, you better be ******* clean. Harbaugh has already called out day on a conference call for practicing when they weren't supposed to be. If you're going to be a narc, the house better be in order and I just really don't think that the top end college football programs are playing by all the rules. I mean, we know they're not, but the people in that industry know more than we do. It's an honor amongst thieves sort of deal and once that's all broken, especially for a guy who isn't part of some greater college football coaching fraternity, it's all free game.
I also understand your point but I don't know that "we know it hurt these teams" and "we know it made them a better team" is a compelling point. The NCAA can't be all like "cheating is cheating" in one scenario and not the other. That phrase inherently gives zero leeway and currently, even though we all knew this is how it'd work, pay for play is being used all over while against the rules, not to mention the spirit of the rules.
At the end of the day the punishment here comes down to the NCAA being a feckless, inconsistent, money grab for a few people who have basically zero way of defending any decision they make. Hammer Michigan? Ok, what are you going to do about X, Y, and Z and why wasn't Q punished for a literal FBI investigation that found wrongdoing. Don't do much of anything against UM because a link couldn't be drawn to anyone in leadership and the buck stopped with Pony Boy? What the hell? They were gaining an advantage. That's why, IMO the easiest way out for them is a fine and probation. They get more money, Michigan is happy because not materially happened and while OSU and MSU aren't happy (they won't be unless Harbaugh is given a 15 year show-cause) everyone else is largely fine with it.
