Police believe Robinson allegedly told some of his players they were being investigated by police and needed to lawyer up.
Beyond that statement by police being completely damning to JRob if true, you don't tell your wrestlers to 'lawyer up' if they were simply users of Xanax. Doesn't make it 100% certain, but it is highly likely that JRob knew a few guys were dealing drugs either before, during, or after his series of meetings/essays. Coverup indeed.
If this did happen and had not been exposed now, and if one of the wrestlers decided to allegedly continue dealing, the risk to MN was great. If one of those pills kills some girl trying to get high, the university is dead because JRob tried to hand out his version of justice rather than use protocol. That's why you have procedures, and why university lawyers don't sleep at night.
I'm guessing you're the parent that blames others for your kids mess up. You quickly called JRob a murderer and forgot about who was really responsible.
