Not too long ago, Josh Anderson was seen as untouchable in the Canadiens. With the team's new prospects and players who are on average smaller and faster, his utility has diminished, especially since he's not finding the back of the net.
However, a player like number 17 still has value for many teams, such as the New Jersey Devils, who would greatly benefit from the physical dimension that Anderson brings.
When Engels talks about two players, he means that Brendan Gallagher would also be a good fit with the Devils. However, I don't believe any team is ready to give Gallagher $6.5 million, even though he has all the heart in the world.
