Good post, I appreciate the actual lay out of your thought process. RNH's production will go up. He was on a 50 point pace last year through an injury riddled season despite playing 2nd fiddle to Draisaitl and McDavid for the year. His biggest issue this year has been poor shooting luck, and poor play from line mates. Pouliot has played horrible and has been his most common linemate, and his RW has been a revolving door of rookies in Puljujarvi (when he was struggling early in the year) and Slepyshev, and role-players in Kassian/Pitlick. He's now on a line with Maroon and Eberle and that line looks great. They've been a scoring threat every night since being reunited and if Eberle could hit the damn net with all his high quality chances and Maroon could get some puck luck (has like 3 or 4 posts in the last few games) then RNH's production would have already taken off. I still think he'll score around 50 points when the seasons all said and done (assuming he's healthy). His play away from the puck and in puck battles has been outstanding.
It's from all of the years of arguing Stastny's value, and how much his production fluctuated depending on how dangerous his wingers were. He'd always elevate guys, but he couldn't put the puck in the net for them as well. Stastny was also asked to play against more difficult competition during that time too.
Stastny made 6.6M, and we were fine with him most years. He was a touch overpaid, but not enough for us to trade him for Bozak + 2nd lol.
RNH makes 6M, and is way younger with more potential, so it's easy to see. That and MacK's chemistry with RNH is probably why more Avs fans have come around to being ok with RNH for Barrie.
