Quoting: TMLBRIAN
funny 2 other posters in here said the opposite. I think Chychrun is a solid top 3 dman who is making less money than he would normally get on the open market. I think both teams consider this. But maybe you are right that Arizona needs to pay more.
I don't think he's a bad player at all; I think your assessment of him being a solid top 3 D is spot on, and his contract/age definitely work in his favor.
I just think #2OA, even in what most folks think is a mediocre draft, is still very valuable. Let's take the 2019/20/21 drafts out because most of those kids are still super young and haven't had a ton of run yet (Kakko/Byfield/Beniers with 2 of those 3 looking like good prospects and Kakko looking solid if not spectacular) and look at the 10 #2 picks between 2009-2018:
2009: Victor Hedman (Norris Trophy & Conn Smythe Trophy winner)
2010: Tyler Seguin (305 goals in 825 GP - pretty good!)
2011: Gabriel Landeskog (248 goals in 738 GP, Calder Trophy, captain of a Cup Final team)
2012: Ryan Murray (even in a year when everyone missed the top 4 guys, still has 432 GP in his career)
2013: Sasha Barkov (Byng Trophy, Selke Trophy, 220 goals in 596 GP)
2014: Sam Reinhart (167 goals in 532 GP, finally a PPG player in Florida)
2015: Jack Eichel (153-227-380 in 409 GP, consensus #1 in any year w/o McDavid)
2016: Patrik Laine (176 goals in 407 GP, PPG this year with CBJ)
2017: Nolan Patrick (ugh - 77 points in 222 GP, ruined by head injuries, shoulda been Tkachuk or Hughes)
2018: Andrei Svechnikov (89-120-209 in 283 GP, loves scoring cool goals)
I'd say 8/10 of those dudes are bonafide top line players - Ryan Murray is an obvious miss and Nolan Patrick is a miss with an asterisk because he's still young enough to come back from these injury woes and turn into a solid player. But basically saying you've got an 80% shot of picking a top line player is, to me, worth more than the package the Devils would be picking up in this deal.
