With refs swallowing their whistles, resulting in power plays being near or at all time lows, and with replay determining more and more plays on the ice, does the NHL still need to have 4 officials on the ice? Fights are also become rarer so the need to have 2 linesmen there to break those up will decrease.
The 2 referee system is not that old according by NHL standards.
