I can't believe I am going to defend the Capitals... but here I go:
First, I do not think ANYBODY wanted to be in the bubble in the first place. Second, I am not surprised that guys are trying to make the best of a shitty situation. Third, if you think hockey players do not party during the regular season or the playoffs, you are mistaken. These guys are FAMOUS humain beings in their 20s and 30s with a lot of money; of course they live the life. I mean, hell, I remember my early 20s and I did plenty of partying... but never missed a day of work. Plenty of us have.
I mean, I am sure you have guys who stayed in their rooms and played videogames until 3AM. Older guys with a wife and kids probably spent A LOT of time of facetime. The Caps may have a "funner" bunch than most and were hanging out more. Who knows and who cares? These guys are not robot and they are allowed to have fun when they are not working. Same as everybody. Does not mean they are not taking things seriously.
One thing I am 100% sure of is that every player and every team played to win once they got on the ice. That's how these guys are wired and if they weren't, they would never had made it to the NHL.
