Thanks for answering. First of all, the Leafs have been very good for four of five years now, so I agree the 2020-2023 teams are not easy to be improved upon.
Over that three year window, it was very much the core four leading the way for the forwards. They were supported by a supporting cast that included a 15-goal Hyman (in 55 games) and then Bunting, Mikheyev, Engvall, Kampf, Spezza, and Kerfoot. The defense was Reilly with Brodie, Giordano, a hobbled Muzzin for a while, Holl, Sandin and Liljegren. Our goaltending was a revolving door of Campbell, Andersen (splitting the Covid season with Campbell), Mrazek, Murray, and Samsonov.
With that window as the benchmark, I would say that three of the core four have hit their primes and improved every year, our next tier now includes Knies, Domi, McMann, Robertson, Kampf, Jarnkrok and Holmberg. Even with Tavares losing a step I would say our F this year get the edge over the the benchmark.
As for D. I won't pretend to forget that Brodie was pretty good and Giordano was useful. I would say they are more than replaced by Tanev and McCabe, Benoit gives us more than Muzzin was able to, and OEL and the more mature Liljegren over Sandin and Liljegren. Edge to this year, no?
It's almost amazing we have been as good as we have when you list our goalies over that period. Woll and Stolarz should the best tandem since Campbell/Andersen the Covid year. That has to be a draw or edge to this year.
We also have a new coach and those often come with improvement for good teams.
