I think that celebrations in hockey should be as accepted as any other sport. Hockey always has this stigma of being a hard hitting rough and tumble sport, but in reality, it's still a sport at the end of the day and to expect players to simply score a goal or win a major game or win a championship and have no reaction is outlandish. I do believe that there is a line that shouldn't be crossed when celebrating, like in MLB or NFL or any other sport, but celebrating is part of it at the end of the day. The NFL recently loosened the rules around celebrations in an attempt to make the league more fun and less restricting, and given that the NFL oftentimes stands for the No Fun League, I think it's totally reasonable to still have players skating around in jubilation, being mobbed by their teammates, etc., as long as it doesn't take longer than could reasonably be expected for the puck to be reset on the ice. Otherwise, let the guys be happy!
