Here read Bob MacKenzie article
Now it gets interesting.
Number three is to play an 82-game schedule next season using exclusively replacement players, that is, any players outside of the NHLPA membership who want to play under whatever terms and conditions the NHL decides to set. A collective bargaining agreement would not have to be in place. In fact,
no NHLPA member, even if he wanted to, would be permitted by the league to cross a line and play in this circumstance. Number four is the same as number three, but a reduced 60-game schedule, which might make more economic sense.
Number five is to play an 82-game schedule next season by declaring legal impasse, implementing a new CBA and using a combination of replacement players
and whatever NHLPA members who would cross the line to play.Number six is the same as number five, but again, with a reduced schedule to 60 games.
