I suppose it doesn't help that JB refuses to offer much insight into what it is that happened? The players that allegedly broke the team rule (not NCAA mandated rule) surrounding marijuana usage and weren't suspended are reportedly forming the basis for some of what is before the infractions committee.
So if he MG broke curfew Thursday night or skipped a mandatory class or meeting, then I agree no biggie, it happens and who cares. But, JB hasn't historically been a disciplinarian, so when a player has to sit out a game it has usually been a bigger issue than simply a "team thing" with no further consequences.
Of course, I am in the let it play out and if he's playing on Sunday let's not worry about it camp. But, I said what I did above because I understand why others may react the way they do/did.
