From what I hear, the melee was pretty minor. Not good, and suspensions likely, but not much to it and its being somewhat overblown.
What concerns me is that a gambler, mad at losses betting on UF, has any connection to the team or its players. Many theorize that there is a lot of shenanigans going on in college sports and occasionally there is a controversy about a basketball team engaged in points shaving.
I know it goes on in lots of places, but you just cannot ever have that stigma associated with your team, it undermines everything you do. If any of these folks are tied to this guy in anything past acquaintance level, then frankly I think they have to be shown the door even if there is no direct evidence of wrongdoing.
They'll all land somewhere else. But we cannot take the risk of it becoming such a distraction.
