Anyway - I don't think you can justify having Richard at #5, and frankly I think he's hard to justify in the top #10 the more I look at it.
A few things to back that up -
First - I'm sorry but zero Art Ross trophies despite playing his peak years in a shallow league is a huge mark against him for me. Yeahyeah Richard Riots but the fact is he was never #1 in points. He also only has one Hart (again despite diluted talent in the early league). While trophy counting is far from #1 to me, we're talking rarified air here so you should at least have some scoring records to your credit.
Second - Five retro-Rockets doesn't put him in top goalscorer territory for me (to make up for his lack of Ross trophies). Good numbers, but clearly behind Bobby Hull and Alex Ovechkin as goal scorers, not to mention Gretzky and Mario. He's more in the Bossy-tier of goalscorers to me. So I don't think we get that "rarified air" feel from him like you do when looking at others.
Third - Key player on a dynasty, yes, but most of those Cups come when Richard is by far in the twilight of his career. JB, Harvey, and Plante were probably bigger factors in most of these seasons (and 59 and 60 he was barely a contributor), and he's probably behind his brother in part of that dynasty as well.
The mark in his favor is his playoff performances. He has a few that stand out. 12 goals in 9 games, 11 goals in 10 games, 9 goals in 11 games. All great runs. 82 goals in 132 games is impressive, and he was roughly a point per game which I think is pretty damn good for that era. But where does that put him against the other guys on this list?
I think we can agree that Roy is above him in the playoffs. It's probably a better total resume than Hull (although Hull has a couple of worthy runs). JB? I think JB gets the nod here generally for being a key part of 2 dynasties (with numerous remarkable performances on each end of his career). For playoffs I'd put him clearly above Hasek, Shore, Morenz, and Bourque, but clearly behind Roy, JB, and probably around equal to Sid and Harvey (without having looked more closely at DH's playoffs).
So we have *probably* the worst regular season player of this group of ten (if nothing else bottom two with Bourque), and *maybe* top 3 - top 5 in playoffs of this group.
Without starpower, I don't see how you can say Richard is a top 9 player in hockey history.
