NHL trade activity has been limited this season because of the stagnant salary cap and the requirement that traded players quarantine first before suiting up for their new team.

But it could pick up with the April 12 trade deadline quickly approaching. 

Contenders will get their last shot this season to improve their teams for a playoff run, and bottom-rung teams will be able to load up on prospects and draft picks to aid their rebuilding programs.

Plus it's another opportunity for teams to get their rosters in shape before the Seattle Kraken's expansion draft July 21.

A look at teams that could be active:

Sellers

Buffalo Sabres: Though they're playing better since ending an 18-game winless streak, they'll try to get something for their pending unrestricted free agents. Even with his down year, Taylor Hall should get a nice return. Defenseman Brandon Montour could draw interest. 

Detroit Red Wings: General manager Steve Yzerman signed a bunch of players to one-year deals last offseason so he could move them if needed. Bobby Ryan and Marc Staal fit in that group. Other pending unrestricted free agents include goalie Jonathan Bernier and Luke Glendening.

New Jersey Devils: Their potential UFAs include Kyle Palmieri, Travis Zajac, Sami Vatanen and Dmitry Kulikov. The Devils are holding Palmieri out of games as a precaution.
