The Rangers are 4 points behind Boston. Boston has 17 games remaining and we have 15.
Our last 2 games of the season are against Boston, and Boston plays their extra 2 games after that. We need to be tied with them on points, or better, by the time we play them. If we do that, we control our own destiny. So we need to make up at least 4 points in the standings between now and then.
Boston's schedule: Sabres, Islanders, Islanders, Caps, Sabres, Sabres, Sabres, Pens, Pens, Sabres, Sabres, Devils, Devils (Rangers, Rangers, Islanders, Caps)
Rangers' schedule: Devils, Devils, Devils, Devils, Islanders, Flyers, Flyers, Sabres, Sabres, Islanders, Islanders, Caps, Caps (Boston, Boston)
That's 13 games for each team before we play each other, and we need to win at least 2 more games than them over that stretch. Only 1 of our next 9 games is against a team ahead of us in the standings. We can put the Flyers away and catch Boston at the same time.
