I don't know if we want Heatley. We have Ryder, is he that much better for 3x the price. I think we need youth and speed.
The Devils don't really have anything to give up to get a player like that, unless you're talking about a blockbuster trade of the Larsson for Kane type (that's just a hypothetical example. It doesn't make sense from the Jets' POV, so I'm just expressing the concept).
The idea would be to shed salary for next year and open up a spot for Merrill, who is probably a better option than Sal at this point. Heatley is in the last year of his deal, and I think you could probably find a spot for Heatley on the third or fourth line.
