Gretzky, Orr, Lemieux, Howe, Hasek, and Jagr based on the choices. With Crosby and Hull not far behind.
I also don't know how guys like Richard, who are incredibly overrated, get listed over players like Ovechkin.
I don't know... Ovechkin is probably the greatest goalscorer of all-time

I'm not sure where Richard will land on that list, but it will be high. But agreed there's many guys to consider as well. Personally, I find recent history more impressive than when it was still a small sport in a small populated region. The talent comes from anywhere now and also have to consider goalies equipment and stuff like that (no mask? lol)
Regarding Richard, there's the "mythical historical legend" and what he meant to the quebec population. I wasn't here and my family wasn't here as well so it means absolutely nothing to me but I guess it did for families who have been in this area for a long time.
But what about the other guys? Looking at Adjusted Goals per Game
Cecil Dye : 326 goals in in 272 games : 1.20
Denneny : 392 goals in in 329 games : 1.19
Ovechkin: 835 goals in 1197 games : 0.70
Lemieux : 616 goals in 915 games : 0.67
M. Richard : 653 goals in 978 games : 0.67
Bure 463 goals in 702 games : 0.66
Bossy 461 goals in 752 games : 0.61
Bobby Hull : 644 goals in 1063 games : 0.61
Stamkos : 516 goals in 841 games : 0.61
Brett Hull : 738 goals in 1269 games : 0.58
Esposito : 671 goals in 1282 games : 0.52
Gretzky : 758 goals in 1487 games : 0.51
I haven't ranked them all but looking at this, there's several guys that should be in the discussion. Obviously, the first 2 are the outlier, from a very different era.
