Overtime hockey games in the NHL are now 3-on-3 (not including goalies)
Why did the NHL change its overtime rules?
Overtime games in the NHL are now 3-on-3 (not including goalies), down from the 4-on-4 extra periods of years past and the 5-on-5 regulation-time lineups. In theory, fewer hockey players on the ice will create more space and more scoring opportunities. The NHL would like more sudden-death goals and fewer shootouts, so it introduced this rule change this season. Only time will tell if the drastic step has the desired impact.
