You don't know what was in that NOA other than what Michigan has selectively leaked.
Naturally what Michigan leaked has been meant to minimize the issue in the public eye. Michigan's suspension of Moore is simply an attempt by their crack lawyers to plea bargain prior to the 3rd party commission. Remember when you were telling the forum those crack lawyers were gonna sue the pants off the Big 10 and NCAA? LOL
"Punishments against a lot of former staff" is a distraction and has nothing to do with what Michigan as the institution still faces.
Michigan itself faces "A Lack of Institutional Control" and/or "A Failure to Monitor" which allowed the 'Illegal in-person scouting of future opponents scheme'. Had Michigan self-reported than this would be a different issue but they didn't.
i.e. As an institution, Michigan is ultimately responsible for NCAA compliance of their athletic department. Not Harbaugh, not Moore, not Stalions.
