At some point, production has to match skills evaluation. He was evaluated as being a project defenseman with a good shot and good skating ability, but needed to tighten up his defensive play.
He was tied with six other AHL defensemen at 23rd for point production and nothing about his offensive stats stands out at the AHL level. And I was hardly singing his defensive capabilities - my expectation is for him to be competent, but not a standout at the NHL level.
I think if your hope for him is to be a decent cost-controlled defenseman with whatever he generates offensively being gravy, you'll be content with him. If you're expecting more than that, then I think that's unrealistic. Better than Thrun, but nowhere near Dickinson.
In terms of points production, that really doesn't seem bad to me when you consider how bad the Barracuda team around him was, and, like
@jMoneyBrah said, his first full season on North American ice (as a 21-year-old for nearly half the season).
And it's not like his only calling card is point production. He's probably most likely to be an all-around solid 2nd pairing d-man. Will the D take a while to sharpen up? Probably--but by all indications he's getting there (and as someone who's 6'4" or 6'5", he already has an inherent advantage when it comes to certain aspects of defending).
Seriously, if anything, I think people out there are sleeping on Mukhamadullin. He was under the radar behind hotter Devils prospects, was playing in Russia until 2023, and then was exiled to San Jose and a terrible Barracuda team. A perfect recipe for him getting underrated by national prospect evaluators.
