If you believe the guys who are really into advanced stats, goal-scoring declines heavily after you turn 25, and especially after you turn 29. It is the rare player who is an exception...
As I said, I'm comparing Gretzky to the other elite goal scoring outliers, and his career arc stick out like a sore thumb. He was total non-factor on the leaderboards after 28.
Among the other leaders in adjusted goals-
Lemieux- obviously far more effective later on, not even close here.
Howe- ditto
Richard- elite into his mid 30s
Sakic- career high at 31, at age 37 scored 36
Bobby Hull- was 2nd in goal scoring at 33, then left for the WHA. He had a few more elite NHL seasons in him, probably. Better goal scorer than Gretzky.
Jagr- 54 goals at 33.
Shanahan- top 10 when he was 37
Espo- won the Richard at 32, top 10 at 36
Selanne- we all know about him and he's been doing since he turned 35.
Robitaille- reached the top 10 as old as 33, scored even more at 34
Brett Hull- top 10 at 33, top 10 at 38. Filled the net his whole career.
Messier- his best adjusted goal total came at age 35
Dionne- still top 10 at 34
Gartner- Gretzky used to lap this guy, but Gartner was the guy scoring 30-35 into his late 30s when Gretzky couldn't get past 25
Sundin- super consistent, was scoring 30+ into his mid 30s
Iginla- still a top scorer at 34
Yzerman- had a tougher time scoring as he aged, but he has a better excuse than Gretzky (a lot of these can make the same excuses people make for Gretzky's sharp decline)
And we had guys like Bure and Bossy who would certainly have done a lot better as they aged, too, they always had the touch. And two-time Richard winner Peter Bondra did too.
It's pretty damn glaring. Gretzky stands alone here. Despite being the all-time leader, he falls behind literally EVERY OTHER great goal scorer in this regard.
Yeah, Ovechkin's arc as a goal scorer is more the norm than the exception.
See above
And we don't know Ovechkin's career arc, he's only going into his 27yo season. We do know that he's had a rough couple of years, and he just finished a disappointing season, but he was still a top 5 goal scorer, better than the year before. It's very possible, with a better team situation and some personal tweaking of his game, that he gets right back into the Richard mix. He's still an elite goal scorer, it's hardly time to consider his career arc. I expect he'll at least get back to 40 and continue to be a top sniper in the league until a good old age.
