Most 3rd overall forwards are back in junior at this point. The exceptions being Kotkaniemi and Galchenyuk. PLD, D. Strome, Draisaitl (sent back late), Drouin, and Huberdeau all finished the year playing in junior and that is all the 3rd overall forwards from this decade. The only 3rd overall forward to make a big impact in his D+1 in recent memory is Duchene. We will see if this pays off for Chicago or not, it hasn't in Montreal's case. Whereas at 1OA and 2OA we have a ton of examples of guys walking in and being high-end players or at the very least top 6 players. His season was good. He showed an improvement, showed he wasn't overwhelmed and earned more opportunity, and unlike the two ahead of him wasn't just handed an opportunity in the top 6 with top line PP minutes. Even if you look at 4th, 5th and 6th overall forwards from this decade, the list of impactful players in their D+1 is pretty short with it basically being the Tkachuk brothers and Monahan.
Considering Dach was viewed as a 4th to 10th guy mostly at his draft, and he's played competently at the NHL in his given role, and arguably outplayed the other 2 guys taken ahead, I don't know how his season could be labeled disappointing. At worst it has to be average to above-average given the usual return of a 3rd overall pick, and how he's played against his draft peers this year. Maybe he'll take the next steps like Monahan or Barkov, or maybe he'll stagnate like Nolan Patrick or Galchenyuk.
I think there's a fine line between believing a player is on a course to develop into a good player, and also to set what realistic expectations are, and hold that player to it.
I think Chicago made a mistake in keeping Dach in Chicago for the whole season. He probably shouldn't have even gotten nine games. These nine game trials are often a bad idea. Either you believe the player is NHL ready for a full season or they aren't. No nine game trial should influence that because being an NHL player for nine games is much different than for a full season. Many talented prospects can play nine games. Most cannot play 82 games, and that's why they are still prospects.
But I think some good points have been made. Dach showed a better two way game and consistency in effort than was his reputation. His non-elite skating, which was probably the only other knock on him, was nowhere near the weakness in the NHL game for him that it was for someone like Kakko. The areas of the game that were question marks were areas Dach did well in addressing this season. If you bought the strengths of his game to the degree that many did and probably caused Chicago to pick him third, you probably come out of this season rationalizing that Dach is on a good path to become a very good player.
At the same time, all of that is separate from whether he had a good season in the NHL. The NHL is not the minor leagues or junior hockey. You are trying to win. You expect all your players to contribute positively towards winning in the roles they play. Assessing their performance should be based off setting what are realistic expectations prior to any games being played, considering likely roles and other factors within the team, and how their eventual play stacks up to the expectations. I think if anyone said to themselves that his production was what they expected, and is production that they would consider a good season at the NHL level, they are lying to themselves. While offensive production isn't the only part of the game that matters, I think there needs to be a minimum bar of production reached to have a good season.
There are not that many players who've played full seasons or even half seasons in the NHL in their D+1 season. And that's for good reason. Most of them aren't NHL ready, so there's no shame if Dach isn't NHL ready this season. But in the past 5 drafts, we've seen 17 players play more than the 9 games, if I'm counting correctly, 14 of which are forwards. 10 of the 14 have averaged over 30 points per 82 games, so its not a very high bar we are talking about. Players such as Patrick and Kotkaniemi, both of which aren't considered elite young players by most at the moment, cleared that bar rather easily. And there have been some guys who were well above that bar, and pretty immediately were elite NHL forwards.
Dach keeps company in that regard with Puljujarvi, Hughes and Kakko. Thats not good company. A guy most consider a bust, and the other two players from the past draft that probably had even weaker seasons. Why has every other forward who played substantial games in their D+1 season that didn't turn into a likely bust produced offense at what is a pretty low bar? And I'm not saying that means Dach is a bust, but its to say its a very low bar. It's not asking much of a guy picked 3OA, even if he wasn't NHL ready. Most still say Kotkaniemi wasn't NHL ready, and he cleared it as a 3OA. Galchenyuk was sent back to junior hockey as a 3OA with much better statistical production as a 3OA.
You can even assess the D+1 defensemen and say that most of these guys did not struggle to put up points. Defensemen aren't as high scoring as forwards, but Dahlin cleared 30 per 82 games easily. Chychrun and Hanifin, two non-elite scoring defensemen, comfortably were over 20 per 82 games, and these aren't players into the 40's for points now. Their current production entering their prime isn't astronomically better than what it was in their D+1 season.
There are always exceptions. Thornton was one, Draisaitl could be looked at as another. None of this is to say Dach will not be a good player, but I don't think we should revise expectations because we like the player. I was a big fan of Dach at the draft, and I'd argue he projects better right now than the two guys that went ahead of him, but they can all have bad seasons. This doesn't need to be an either/or proposition with the three top picks, and we don't need to skirt around pretty low expectations to rationalize and prop up a bad season for a D+1 forward in the NHL.
