Quoting: Wqrrior
Well, the Isles are in a cap crunch so it would be difficult - however, if Barzal is lost, this organization has no fill in / replacement. They really have no choice but to match it.
Really, if you look at it, they've likely got $13-15 mil to resign Barzal, Pulock, Toews and a backup goalie (Unless Sorokin comes over...dear lord look at those friggin' KHL numbers!), and that's without trading anyone. If you move someone like Leddy, you've still got a decent d-core, and free up more space. Or even move one of Pulock or Toews. They've still got Pelech, Boychuk, Dobson, Mayfield, and Hickey (Maybe move him somehow? Wasn't picked up on waivers earlier in the year, but I'm sure there's a way to make it happen), and whoever of Pulock or Toews that they keep.
Would Monteal offering $10 mil hurt a bit? Sure, but with $71.38 mil spent on 18 players for next season, they've got enough flexibility to make it work. They've also got ELC's in Wahlstrom and Bellows that could fill holes rather cheaply.
