That is just plain false.
Both Ovechkin and Malkin had stretches that were just as good as Crosby's peak 40 games, except Ovie's was better because he sustained it for over 50 games. Same goes for Malkin who scored 60 some points and 30-some goals in a 40 game stretch during 2012:
NHL Stats
Malkin matched Crosby's best 40 game stretch of play ever, except he put it all together within a Hart/Pearson/Art Ross full season.
So basically you are claiming Crosby was the absolute best because he matched,
not exceeded, Malkin, for brief periods, except Crosby contributed precisely nothing in the other 75% and 50% of the seasons whereas Malkin contributed at an elite level, just not at that peak level.
I understand why you are misremembering: Much of Canada acted like what you are saying is true. But it isn't.
