He has 100% without question “regressed”.
This is a kid who as a rookie was noticeable just about every game, even if the production wasn’t there. There was flashes of his potential. And he was almost always one of our better forwards, despite playing a lot with guys like Carpenter in the bottom 6.
Dach legitimately had me excited. I was very impressed by how well he looked in his first season. But these days(and really going back to last season when he made that early return from injury) he hasn’t looked the same. I notice him far less, and those flashes of elite skill seem to be happening less and less as time goes by. He is no doubt worse now than he was when he first joined the team a few years ago.
