A couple of things where we might just have to agree to disagree because I see things fundamentally differently.
1. We had not gained 3 young elite players by 2022. Zegras, Drysdale, and McTavish are very good young players, but not one of them has shown the ability to be elite. Of the three, Zegras has the highest ceiling, but that ceiling isn't even to the level of Getzlaf. Drysdale and McTavish are good 2nd line/2D types, even at their best. That is not elite. Cup-winning teams need one or two elite players. Before Carlsson, we didn't have one in the system.
2. I disagree that the team was showing sustainable signs of getting back to being a playoff team by year 4. If you're referring to the run of success in the first two months of the 21-22 season, that was kind of a mirage. They were still getting outshot most nights (sometimes badly), and after that hot start, went 10-16-6 before the trade deadline. I understand the desire to be encouraged by that run (I know I was excited by it), but I don't think it told us much about the trajectory of the team.
The young players have been surrounded by veterans this whole time. Getzlaf, Henrique, Strome, Vatrano, Killorn, and Terry (as he moved from a kid to a vet). If you're asking for better players, I would love them, too, but there lies the dilemma. If the Ducks got better veterans to surround the kids, they would have been drafting in the 5-12 range instead of the 1-5 range. Then they don't get an elite player in the draft and can't compete for a Cup anyway.
