Man what is wrong with McGreggor?

So he was recently involved in an altercation where at least one other fighter received cuts from a broken window having been shattered by a thrown chair by someone believed to be in McGreggor's party.
This is just crazy. There is a level of professionalism I expect from fighters.

Before this it was thrown water bottles at the Nate Diaz pres conference. Prior to that it was that this fool ran out into the crowd to confront Jose Aldo in the stands. Fans who happen to sit near fighters are not just supposed to be ignored when things happen, Mystic Mac runs out into the crowd to square off with Jose Aldo and luckily nothing happened but there could have been much worse consequences. Crowds of people are very difficult to control.

I am so disappointed in this fool's actions I'm embarrassed to be an MMA fan.
