Check out the latest speculation on the Avalanche, Islanders, and Kings in today’s NHL Rumor Mill.

THE DENVER POST: Corey Masisak believes the first-overall Colorado Avalanche will “almost certainly” add another defenseman before the March 6 trade deadline. However, adding a third-line center is a more pressing need.

The Avalanche could stick with Ross Colton in that role. Bednar recently praised Colton’s efforts in his first game in that role. They could stick with him if the cost of finding other options proves expensive.

Masisak suggested former Colorado centers such as Ryan O’Reilly of the Nashville Predators and Nazem Kadri of the Calgary Flames as possibilities. However, the cost for both makes them unlikely trade targets for the Avalanche.

Other options include Alexander Wennberg of the San Jose Sharks, Jason Dickinson of the Chicago Blackhawks, and former Av Charlie Coyle of the Columbus Blue Jackets.

SPECTOR’S NOTE: O’Reilly reportedly isn’t considering a trade at this time. Kadri’s contract and the Flames’ asking price are too expensive. The Sharks won’t part with Wennberg if they remain in playoff contention.

Dickinson and Coyle could be more affordable if the Blackhawks and Blue Jackets go into sell mode. However, the Avs could be forced to overpay if other clubs get into the bidding, and they’ve already sacrificed future assets in recent years.

NEW YORK POST: Ethan Sears believes the Islanders have a steady, left-shot defenseman and a top-six winger near the top of their Christmas wish list to replace sidelined blueliner Alexander Romanov and winger Kyle Palmieri.

If the Islanders become buyers, they could get salary-cap relief by placing Romanov and Palmieri on long-term injury reserve. San Jose Jose Sharks defensemen Mario Ferraro and former Islander Nick Leddy could be blueline targets, while Kiefer Sherwood of the Vancouver Canucks or Matias Maccelli of the Toronto Maple Leafs might make sense as a replacement for Palmieri.

Sears doesn’t see general manager Mathieu Darche parting with a first-round pick to get any of those players.

For now, it’s too early to tell which path Darche might choose. Sears noted that a couple of bad weeks could knock them out of playoff contention in the tightly packed Eastern Conference.

If Darche buys early, he could be parting with future assets that he’ll need to recoup if things go sideways. If he waits too long, he’ll end up in sell mode with UFA-eligible forwards Jean-Gabriel Pageau and Anders Lee.

SPECTOR’S NOTE: Darche will remain patient for now, especially given how few sellers there are in the trade market. The Isles’ performance in January will likely determine which path he takes, especially if more teams become sellers.

The Sharks aren’t likely to part with Ferraro and Leddy if they remain in playoff contention. Sherwood is available, but the Canucks’ asking price could be too high for Darche. Maccelli should be an affordable addition, but his struggles this season don’t make him an enticing trade target.

THE ATHLETIC: Eric Stephens believes the Los Angeles Kings have more work to do after trading center Phillip Danault to the Montreal Canadiens on Friday. He noted they didn’t get a roster player back in the deal, and the club continues to struggle offensively.

Stephens pointed out that the draft pick they got in the Danault deal would look good if the Kings were rebuilding. However, the club is built to win right now, and they still believe they can reach the playoffs and make some noise.

That second-round pick will only be valuable if it can be turned into a player (like Ryan O’Reilly of the Nashville Predators or Brayden Schenn of the St. Louis Blues) who makes the Kings better.

SPECTOR’S NOTE: Kings GM Ken Holland probably isn’t done making moves. Stephens pointed out that they shed Danault’s $5.5 million cap hit for this season and next, giving the Kings $9.2 million in current cap space, and a projected deadline cap space of $26 million.

As mentioned earlier, O’Reilly isn’t prepared to consider a trade right now. Meanwhile, the Blues intend to seek full value for any player they trade, meaning they’ll want a young NHL player for Schenn instead of draft picks.
