Do you actually believe the strength of schedule argument because I don't.89 very well could be enough. It'd take one of the 4 teams were competing with to play just above 0.600 hockey for it not to be.
Detroit has the strongest strength of schedule in the entire league, so they're likely done. Islanders are 4th and they sold at the deadline, so I can't see them doing it. It's going to depend on what Columbus and the Rangers do in the homestretch.
There are far too many variables that get overlooked.
Nothing can predict what a team will have in the tank or the effort they will put forth on any given night.
For me the exercise is very much a one game at a time proposition and take nothing for granted.
