If the Canadiens are talking a trade with the Jackets, I personally would have to believe that a defenseman would be in the works. While on paper they're fine; at the close of the year they only have three of their current eight defensemen under contract (Gorges, Emelin, Drewiske). At the top of their list of priorities there will be getting P.K. Subban locked up long-term; which certainly won't be cheap. After that, they are set to lose Markov, Bouillion, Murray, and Diaz ... of those four, it's likely that they'll either keep one (most likely Murray?), or sign a free agent ... after that, I think they turn to a younger player such as Nathan Beaulieu or Jared Tinordi to fill out their lineup.
My point in all of this rambling? Maybe an expendable bottom pairing guy for us (Nikitin, Savard, Erixon) could be a huge pickup for them, as all are fairly young and could possibly be retained for less than a free agent would for Montreal.
If they're interested in Umberger, as is rumored, then that's great ... but the Jackets will have to take back one of those salaries if they're going to get rid of the albatross deal that is RJU. If this rumor is true, then I think that any of the "mighty mites" for Montreal could be in play ... be it Briere, Desharnais, or even Gionta.
All that being said, I highly doubt anything other than a minor deal comes from this.
