I disagree. He clearly has those skills to my eye (except puckhandling, which surprised me. That's clearly gone down the drain). I mean, I see him make really impressive passes, and he's got the third fastest acceleration on the team after McDavid and Hall. His top-end speed isn't great, but he consistently impresses me with his bursts of speed. Even last game, he was out for a while and people thought he re-injured the ankle, and then he comes out with a burst of speed and the GDT thread a bunch of "HOLY CRAP YAK!!" posts.
You don't score goals like this without amazing hand-eye:
I've seen him bat pucks mid air every few games too, they just don't usually go in the net and this is the most easily-found and memorable one. I believe he scored another mid-air goal this season too.
The deterioration of his skills I feel must come from what he's doing at practice - I expect his post-Krueger coaches, especially Eakins, have made him do defensive drills all game long. If you don't practice every day, your accuracy goes down, your stickhandling goes down. Just happens.
EDIT: this is a great quote that I agree with
As for why the scouts slipped up - he put up huge numbers, Galchenyuk (imo the only real contender for 1 OA) got hurt and was out all season, and projecting forwards is so much easier than projecting defensemen that they almost always get picked after the top forwards. Murray, frankly, just wasn't stand-out enough to be considered over all-world natural talent Nail Yakupov. Even Seth Jones dropped and I thought (and still think) he was worthy of going ahead of awesome talents Barkov, Drouin, and MacKinnon. The hockey IQ thing got brushed to the side because people were drooling at how much raw talent he had. Even if you go back to the old reports, it was always marvelling at his shot, his skating, his passing. Very little on positioning etc.
