Burke doesnt want to get 'rid' of Kaberle. He has been willing to hold onto him for as long as he needs to, it wouldnt surprise me if he never traded him at all. Remember, he wouldn't move him for Kessel at the draft so Clarkson and Rolston will not cut it.
Kovalchuk's rights dont really have any value, especially the sort of value to Mueller who did excellent under the Avs last season. They dont want to trade Mueller and especially for the rights of a player who wants to test free agency.
Brendan Morrison doesnt have much left, he certainly can't play the top two lines and third is questionable. Better than Nieds? Yeah, but don't expect him to put up 40 points here, maybe 25-30 is reasonable. I'd pass on him.
Also, Stephen Valiquette? Seriously? The guy was awful this past season, he was put on waivers and it was obvious noone wanted to pick him up. Spent half the season in Hartford playing poorly.
