I REALLY want Matvichuk... he's a guy that we really need. A hard hitter, a crease clearer, he's perfect. Madden or Draper would be incredible too, there maybe the best defensive forwards in the league.
One of Murray, Kovy, or Palffy would be nice as well, as would the Big E.
I agree I think he would be a extremely great pickup for the leafs. Matvichuk is an under rated defenseman who will get alot of interest from teams around the league if Dallas does not try and sign him up before the FA season starts. However I do expect them (Dallas) to sign him unless he really wants out.
