The table below looks at what teams records would have to be from here on out in order to reach 54 points, the assumed number necessary to make the playoffs. The normal assumption is that it will take 92 points in an 82 game season, but a simple 92/82*48 calculation gives you 53.85, the target number for this season.
So teams like Anaheim, Boston, Chicago, Montreal, and Pittsburgh are the only teams that can potentially carry a losing record and still qualify for the playoffs. While this might not be a concern for Boston, Chicago, and Pittsburgh, it is interesting that hot starts for the Ducks and Habs may already be enough to separate themselves from the bubble teams.
Other teams like Buffalo, Colorado, Edmonton, Florida, the Islanders, Philadelphia, Washington, and Winnipeg would all require winning percentages over .600 to get them into the playoffs. Of that list you'd assume the Flyers might have the best shot, but with a poor start and one of the toughest divisions it's a safe bet on them becoming a lottery team.
None of this has much bearing on anything, but with the Leafs only needing to manage two wins over .500 certainly keeps the playoffs look attainable, as opposed to the uphill battle the team normally faces with 28 games left.
