Can we stop with this already? The comparison is laughable.
Jagr was great. He was also a non-factor with strikingly low compete levels whenever the games mattered, and nobody was afraid to play him in those circumstances. Forsberg, Sakic, Lindros, and others (Messier in the early '90's... hell, Kariya, half the Red Wings) were all consistently and repeatedly better players when the chips were down. Jagr is the greatest and most supremely talented passenger to ever play the game. He had "generational" tools and yet struck fear into nobody as a team leader or in "the big game." In fact, he never really even got into any of those unless he was playing on absolutely stacked teams. If you want to include the 1998 Olympics, let's be real: he wasn't a major factor. He was 20th in tournament scoring with 5 points (1 goal, 4 assists) and everything hinged on Hasek and the defensive structure used to support him. He was tied with a guy named "Pavel Patera" from his own team in points and behind him and Martin Rucinsky in goals.
Crosby led teams at all levels to the promised land and was always the most feared player on the ice when the chips were down. That includes Malkin's Conn Smythe year, when Crosby was the defensive priority in every single series they played, which decidedly worked to Malkin's benefit. McDavid is much closer to that than he is to Jagr.
