Most important thing is players stay healthy.
Lots of fans assume this will be terrible, and players won't play hard. Could be. But these players could've opted out if they wanted to, or taken the extra time to heal an injury they want fully healed for the return of the regular season. It's only a handful of games, and these are some of the best players in the world. If they play like they care at all, if they've got any pride, it could be fun to watch. I'll watch, and if it is that bad, I'll stop watching. There's been no NHL players in the winter olympics since 2014, this isn't the same, but it's a potentially interesting international competition and those rarely happen.
