Let's assume that the investigation was over before draft night. (It wasn't, but play along.)
Let's assume that what they are saying is true about the NCAA having to notify them if they are under investigation. (I don't know if there is a bylaw, but I'll pretend there is for arguments sake.)
Why would the NCAA "break" their own bylaws? They wouldn't. They would approve a temporary suspension of that bylaw (through a committee or something, I suppose) because this was a special case where they needed to act without UNM's knowledge for as long as possible. Why? Well, the last time UNM was under investigation and received a NOA, UNM called reporters to give them "an anonymous source" full of lies. So why should they let RR know to get their affairs in order and wash anything that could be corroborated by any past recruits. (Change tags, store layout, etc)
Keep grasping at straws Bears. You should hire a real lawyer instead of an ambulance chaser to represent you......I mean RR.
