I obviously meant skill level/points.
Just b/c Marchand was 6th in goal scoring, doesn't mean he's anywhere close to being in the Kane, Benn or Tarasenko talent level; so who ever made that initial argument is silly. Marchand's a very good player (much like Alex Burrows in his prime), but like Burrows, Marchand is a "passenger" on a line that needs very good linemates to be the "driver" for him to succeed. He's probably in the top-45 to 70 range in terms of forwards, whereas Chris Tanev is around the top-40 to 50 d-men. Anyone that thinks the value is off for Boston is out to lunch. Top-pairing d-men are the hardest players to acquire, and a premium is usually paid to get them.
Anyway, this is not a trade I ever see happening for a variety of reasons on both sides.
