Sadly, we have the 2nd least amount of Cap Space of all teams in the NHL. Any deal would more or less have to be cash out/cash in. With the uptick in Freddy's play he is a bargain contract- don't want to lose that. Marjo, for all the complaints, is fairly paid at 2M. I'd far rather have him than Devin Shore, and Ohgren isn't ready yet. Even then, you'd just save 1.2M at most trading him. You can argue that Hartman is overpaid at 4M, but he's got a NMC, and he provides some sandpaper to the team that it needs. Even a guy like Merrill only makes 1.2M... that's just a hair above replacement cost(Hunt 830K).
The only salary, to me, that is losable is Trennion(3.5M). I see his value at about 2M as a 4th line crash banger. Maybe add in Merrill, and you get almost 4M in cap saved which can be applied to the player coming in - most players of note make more than that, even if BG was willing to admit his mistake and move Trenin.
