I truly think people overrate Kapanen because of his skating being so elite, they think "there HAS to be more there" when in reality he was given every opportunity. It's rumoured both Tavares & Matthews both requested not to play with him, and it's really hard to blame them with his horrible vision and passing.
Production-wise it will be hard to replace a guy that can put up 40 points on the 3rd line, don't get me wrong. His impact though was barely above average in 2018-19 (+ driving offense, - defensive play), and actually quite horrible in 2019-20 (-- offense, -- defense), and really the 2018-19 season looks more like "best case scenario" than "likely outcome" going forward. I doubt he'll be as bad he was this past season, but I think Dubas sold him at the right time, regardless of how much I like him and believe there is something more with him.
To put how bad his season was into context, of the 157 forwards to play 800 5v5 minutes last season his overall rel.xG/60 impact ranked..... 155th. His closest comparables?
Evgeny Kuznetsov (guy always has horrible impacts, but strong production)
Dustin Brown
Miles Wood
Chris Kreider (only negative impact season of his ENTIRE career, I was shocked to see him even close to here)
If you want to expand the search to 500 minutes there are 329 forwards involved, he ranks 312th. The closest guys are:
Frederick Gauthier, Robby Fabbri, Melker Karlsson, Dillon Dube, Jay Beagle, Kyle Turris, Luke Kunin, Nate Thompson, Sean Kuraly, Dustin Brown, Michael Dal Cole.
I'm sad to see Kapanen go as he was one of my favourites, but I'm pretty confident we'll get better play out of 41 year old Thornton, or Vesey, or even Simmonds.
The deal Dubas got for him even taking into his potential to bounce back I think was pretty much a steal. Hallander is absolutely crushing the SHL but the production hasn't come this season, and Amirov is looking like his floor (at least imo) is Kapanen.
