Lots of blame to go around including the gens and coach DJ Smith who is know to be one of the more vocal coaches in the league.  He should of had his players avoid all confrontations regardless since the game was won and why risk injury or possible suspensions.   Once you have a game won you can start giving your top players less ice time.

Discipline is vital for any team especially those with a chance of winning a championship.  Any players who does not follow it needs to face a consequence from the coach regardless of who it is.
