At 5pm ET, the NHLPA announced that 40 restricted free agent players have elected for salary arbitration this summer. This process allows each player and the team that holds their rights to go before a neutral arbitrator in order to come to terms on a contract for the player.
How this works is the team and the player’s agent each put forth an argument for why the player in question should get more or less money. This is infamously a messy process where the players or the team can hurt their relationship, but it is not common that disputes get personal.
