I don't know if this has been posted already, but
@bellagiobob 's post over in the PGT sparked my interest in GWG per GP.
Here is the list of the top 15 players all-time (>25 GWG total) in GWG per 82 GP:
(I included their birth years for reference)
1. Cy Denneny (1891) 12.46
2. Babe Dye (1898) 9.04
3. Connor McDavid (1997) 8.91
4. Nels Stewart (1902) 8.83
5. Mike Bossy (1957) 8.72
6. Auston Matthews (1997) 8.64
7. Carson Cooper (1897) 8.06
8. Alex Ovechkin (1985) 7.95
9. Aurel Joliat (1901) 7.76
10. Bobby Hull (1939) 7.56
11. Phil Esposito (1942) 7.55
12. Bill Cook (1895) 7.25
13. Brayden Point (1996) 7.24
14. Guy Lafleur (1951) 7.14
15. Brett Hull (1964) 7.11
Other notables: 17. M.Richard, 19. P.Bure, 24. Lemieux, 27. Jagr, 34. G.Anderson, 41. Stamkos ...
Edit: In before someone points it out to me, I don't necessarily expect either McDavid or Matthews to remain as high up as they are once their careers are done. They came into their primes early, and I would expect a healthy amount of years at the tail ends of their respective careers where they will not be able to keep up this pace. Pretty cool to see though, and of course McDavid scores more important goals than Matthews, that is a comparison that can be made
