Not sure what you mean by that. Are you saying you think Kylington’s been the best this year? I’d disagree, but you’re entitled to your opinion.
I would agree with Hox that Kylington has been the best, although I don't wouldn't say Valimaki's been anything short of excellent after a rough three or four games at the start. The way Oliver recovers the puck and then breaks out is so exciting. If we're purely ranking on old school criteria like net front play, then I suppose someone might have Valimaki ahead, not that Valimaki hasn't had some gorgeous breakout sequences himself, but I'm just talking shift for shift. Every time Kylington is out there he makes something positive happen. Stick checks, takeaways, winning races, great breakout plays.
There was a sequence in the previous game where the pressure was coming from the left and Prout was to his right with pressure heading Prout's way too. Instead of throwing a suicide pass at Prout, he rims it hard around Prout's side of the ice out of the zone, and then a few second latter the puck is in our offensive zone. Just great reads like that with the puck on his stick, and he's able to skate the puck out of pressure too.
Finally, I believe that defensemen putting up points is not some negative subject. Minute-for-minute Kylington is already producing points 5v5 at the same kind of rates as Giordano, Hanifin and Brodie, in that ~1.1 P/60 range. Andersson and Valimaki are both sitting down in the 0.4 P/60 range . But that gets handwaved by some as "flash" in some hipster manner.
