Alright, so I watched the entire video and paid attention to the time stamps you gave.
I think the discrepancy between what you are saying and what I am saying is that what you are describing as "nice hands" is his puck protection ability. Which I have already talked about being a high level and a hallmark of his play.
His hands themselves, even in Grant's biased text (he's not an elite dangler), aren't anything more than average. He uses what he does have for hands with his edges and big body to keep possession of the puck, but he is rarely manipulative with his hands, he tends to do most of his manipulations with his head fakes and hips.
What I'd really like to see is Dvorsky have a delay and hands game off of his shot, his shot is never faked for the most part, he's shooting even if it is going to be blocked. Not a bad strategy when he shoots as well as he does.
As far as vision, he makes the first play, he's not a multi layer playmaker, he's not threatening cross-seam or through layers of defenders. He wants to get the puck into the first teammate, in the first pocket of space, even if there may be another play off his puck protection, or deeper into the zone. This isn't against men either, this is his own age group.
The lack of those things is my critique but that doesn't mean everything else he brings to the ice can't make him a productive player, it just caps the offensive potential compared to someone like Smith who's offensive tools, IQ, vision and hands opens up more plays and makes more players dangerous around him.
Hrabal improved his stock, if anything. He got tired and let in two bad goals late, but he was the only reason Czechia was close.
