It is a condescending comment, meant to draw attention to the Referee and the Coaches who were under the obligation of teaching the value of Sportsmanship - but apparently failed to do so.  

Unfortunately, this type of uncontrolled behavior by athletes & fans seems to be the norm that permeates our Sports Culture like a lingering stench.  Sports is for exercise and entertainment, but when it tips into violence outside of the Roman Colosseum, it fails in its moral purpose of the game.  

What really matters is the footage, to see if this teenage "victim" might have thrown the first punch, or the true nature of the altercation that ensued.  

Regardless - "Sportsmanship" has been thrown out the window with the bathwater.  savvy.
