I think a talk can be made about Jagr better competition 91-96 or so, but argument could be made about it being quite injured after that and not necessarily better in the early 00s. And also obviously the timing of it, Sakic-Sundin start their career just before or at the same time, Kane-Malkin a year latter.
In term of raw number, I am not sure they dominated less than Jagr or at least does not feel clear, in pts totals and per game at least for Crosby and depending on how you feel about goals for Ovechkin.
Has for McDavid having an underwhelming career so far, specially in the context of compared to Jagr, is that putting a lot of weight on the 1992 cups versus McDavid ? Not sure McDavid would not have done it and if that fair, because otherwise I do not see it, if anything McDavid as went above expectation and impressed imo, MacK and Kucherov are just really really good at scoring and Matthews scoring goals.
