Can the NHL financially survive more shut downs?
That's the biggest concern about it.
I think they'll be fine if they just shut down for say 2 weeks and schedule the games later... Shouldn't lose any revenue over that. But if they have to shut down and then shorten the season again to say 70 games from 82, that will hurt. And if they have to go back to no fans in the stands for any significant amount of time that will really be a tough blow.
