Yeah, I'm in the boat that has Ovechkin over Jagr.
Ovechkin was battling a top 12 (or so) player all time (Crosby) of all time from day 1 for league supremacy. Complete overlap of their careers. Gretzky was well past his prime once Jagr got out of the shadow of Mario. People talk about Lafleur's short peak, but outside of 95-01 Jagr really only has 1 truly impressive season all things considered. And the difference is somebody like Lafleur routinely stepped up in the postseason but I'm sure that will be countered with Lafleur played on one of the greatest dynasties ever for starters.
Ovechkin can hang his hat on being one of the greatest goal scorers in the history of the hockey. For all this warts Ovechkin's hardware is plenty impressive at this stage and the warts he has, Jagr has as well, if not more so.
Jagr was battling Lemieux (probably lost a ross + hart to him in 96) whose a top 4 player
Jagr was battling Hasek (lost 1 hart to him)
He also beat for various trophies peaking Lindros, Hasek, Sakic, Forsberg in his career.
Ovechkin did face Crosby from day 1 - but strength of competition, Jagr wins.
You mention Lafleur's short peak. No Lafleur had a pretty long peak (6 seasons), but he had a short prime (6 seasons? Maybe you add a couple). Jagr had a pretty long peak and a very long prime.
Daver did a breakdown of relevant seasons among the 4 offensive forwards in this group
Here
I don't necessarily with his placement of seasons per tier (honestly haven't had time to look at it in-depth yet)- but it's a good representation at the very least of #seasons worth counting:
Lafleur - 7
Esposito - 9
Jagr - 11
Ovechkin - 11
Jagr is definitely ahead of Lafleur.
Goal-scoring is nice but we shouldn't penalize Jagr for having a more well balanced offense. Overall offense Jagr is ahead of Ovi.
I'm sure you can get to Lafleur > Jagr is you value playoffs VERY, VERY high. And if so that's fine. But if not - i don't see it.
