I still don't think the punishment fits the crime.
After the initial incident, he was banned from the residence halls. 11.5 months after this ban, and only 0.5 months before the end of the ban, there is a miscommunication and he violates this minor ban. He then receives an ALL-CAMPUS ban? Violating the residence hall ban 15 days early after a miscommunication entails a full-campus ban? This basically kicks the kid out of school, kicks him off the team, invalidates his athletic scholarship, and burns a year of eligibility. All this time, he has been going to counseling, presumably getting good grades, and not getting in any other trouble.
Again, I don't think the punishment fits the crime.
