And then Cincy took it the next level with the skinny scrub flying off the bench throwing haymakers. So in order, I think we can go:
Step 1: Xavier's fault (Holloway talking smack to some nobody freshman all the way up the court) - opens the door for an incident
Step 2: Cincy's fault (the nobody freshman making contact with Holloway) - opens the door for the incident to get physical
Step 3: Xavier's fault (second guy in) - opens the door for everyone else to get involved
Step 4: Cincy's fault (crazy scrub throwing haymakers) - turns it from a possible pushing/shoving incident into total brawl
And then we get Yancy Gates and the stomper to put the cherry on the sundae, plus the two Xavier guys throwing punches at the skinny scrub, who was being restrained - if one of those landed, it would've been just as much a cheap shot as Yancy.
