ask for Brendan Shanahan's office.
cite league rule 28.1
28.1 Supplementary Discipline – In addition to the automatic fines and suspensions imposed under these rules, the Commissioner may, at his discretion, investigate any incident that occurs in connection with any Pre-season, Exhibition, League or Playoff game and may assess additional fines and/or suspensions for any offense committed during the course of a game or any aftermath thereof by a player, goalkeeper, Trainer, Manager, Coach or non-playing Club personnel or Club executive, whether or not such offense has been penalized by the Referee.
Bettman and Shanahan have the rule in the rulebook to discipline Emery.
I say this as a lifelong fan of hockey. I believe that fighting has a place in the game, when done right, by two willing participants.
Holtby had nothing to gain by getting into a fight with an amateur boxer. Holtby is the #1 goalie, Emery is the back-up on the 2nd worst team in the league. He repeatedly told Emery that he didn't want to fight.
The league should suspend Emery and the they should publicly discipline referee, #38 Francois St Laurent, who steadfastly refused to allow any Caps player to intervene.
