Misyul kind of stagnated last year but is still young enough to be something. By comparison of the two "other" Russian defensemen in the Devils system (not including Mukhamadullin), it seems Zaitsev had a bigger role for his respective team than Misyul did.
That could be due to myriad factors so it will be interesting to watch how things go this season.
Zaitsev has two seasons on Misyul and KHL site has his total minutes at ~16m this season (58 GP), ~16m last season (58 GP) and ~13m in 2018-19 (47GP). He got ~9:30m at 19 in 2017-18 (28GP).
Misyul had ~10m last season (46GP) after getting -9m (35 GP) at 19. So, yeah, we would like to see a jump in Misyul’s ice-time (though this total ice-time and I don’t know their ES time).
I was even more bummed Zaitsev didn’t get a bigger bump in ice time, the older defensive defensemen (Gavrikov, Lyubushkin) who come over tend to play clear top four minutes by 23. Yes, he’s very long distant shot, particularly since he’s not that big, but hope springs eternal.
I think Walsh has time, there’s two years on his ELC and he only played 33 AHL games last year. He can play big minutes in Utica, my guess is he gets some NHL games in, maybe to showcase him if we do want to trade him. I’m not heavily advocating it, but the advantage of playing guys in the NHL is that it gives them value, I doubt Colorado would give a shit about Maltsev if he didn’t play 33 NHL games last season (with distinction of course).
