Some thoughts. It is possible to be both a culture and structural problem. Culture because Mel Tucker has to clean up a lot of leftover stupidity from the Dantonio era, and Little Jimmy needs to knock off the whining. It's a lot like when Jerry Kill and Paul Chryst had to clear a lot of leftover stupidity from the Bret-Brew era.
My first thought is that the Washtenaw County Attorney's Office wouldn't spend much time on this. However, I was out of town and didn't see any of the videos until yesterday. I've since upped the likelihood of criminal charges to 50/50. Running your mouth doesn't warrant an escalation of force.
The retention of counsel by the beaten up player will be for civil actions against the aggressors, MSU, and UM, not pressing of charges.
When a system is failing at a 3-times-of-7 clip, with frequent reports of past problems of a similar nature, this is a structural problem with the system. I'll readily admit to not knowing what the subgrade looks like below Michigan Stadium, but the University better start finding out.
