Assuming this is a later season trade, the Habs would have no cap issues fitting in Edler, so no need to include Markov (I see that as basically a straight up trade now, Edler is not the player he was 3 years ago). Plus he has a 12 team NTC and VAN may be on it for all we know.
Yeah. Markov as part of an Edler trade doesn't really make much sense for either team.
Canucks don't need Markov. Does nothing for them...and since he's actually still a quality player, it'd just eat into the return in futures pieces they'd
actually want in any sort of Edler deal. It'd be a hassle trying to flip Markov somewhere else for picks/prospects...when Montreal already has the sort of other pieces that would be far more attractive in the first place. Keep it simple.
And for Montreal, dealing Markov for Edler would make the move a lot more lateral, for no good reason. Especially if Markov ended up flipped back to another Eastern Conference contender.
Makes far more sense on both ends to work any potential Edler deal without including Markov. If it happens later in the year, the salary situation gets a lot easier to shoehorn in there without such a significant cap dump/cap offset coming back. And realistically...an Edler deal isn't happening until later anyway, when the Canucks are clearly out of the playoff hunt (if an Edler deal is going to happen at all - he may well exercise his NTC).
By Christmas time or later...the Habs could probably squeeze Edler's $5M in there with only a bit of salary coming back the other way. Beaulieu's $1M would probably do the trick and might make a lot of sense - as an RFA, his salary will surely be going up quite a bit next year anyway, in addition to requiring expansion protection Habs won't have available (Weber, Petry, Edler would likely be the guys, no?).
Or at the deadline, you might even be able to work a pure futures/prospects/picks type package and still squeeze Edler's money in there with some creative accounting. Though Edler if he moves, would surely fetch more than just a likely very late 1st and a good but not great prospect. He's a top-pairing defenceman with two more years on a very good value $5M contract.
