As of Tuesday afternoon, they are one point out of a playoff spot in the Metropolitan Division. This is a Devils team that is under .500. That doesn't speak highly of the rest of the division and the other teams below them. Besides the Capitals and Penguins, no other team is that much of a threat to run away with a playoff spot. The way the team has traditionally operated, the Devils would have to be 20 points out of a playoff spot for GM Lou Lamoriello to consider having a firesale.
The other point is, they really don't have any assets to ship off. As far as players that would actually be attractive on the trade market that the Devils would realistically part with, the only guys that come to mind are Jaromir Jagr and Michael Ryder. And Martin Brodeur (I kid, I kid).
The team we saw for the first seven games is long gone. Over the last few weeks, we've seen this team claim victories against quality squads like Pittsburgh, New York, Boston, Tampa Bay, Los Angeles and Anaheim. The team's current chemistry is unparalleled to the team we saw in early October. This most recent run and an urgency to not miss the playoffs for a second straight year has stamped them as a franchise whose management will do everything to get them into the postseason. This team isn't going anywhere in terms of falling out of the playoff race.
So when you throw in the weak division, the Devils quick rebound to relevancy and their lack of trade chips to begin with, there's no chance this team will be sellers at the trade deadline.
