I'd have Curry no better than 4th, behind Magic, Robertson, and Stockton. I'd say at this point he's comparable to Isiah Thomas and Chris Paul.
Cousy is just from an era so long ago it's nearly impossible to compare him to any modern player, so I'm not even sure where to rank him. Heck, even Robertson, is perilously close to being from so long ago he's hard to compare. But his stats and impact were so overwhelming, I can't leave him off the list.
I believe in Robertson's greatness because even with a much less watered down league, he was putting up numbers it took decades to match. That speaks to me.
Yeah, Robertson dominated his era to a degree less than a handful of other players have in the entire history of the league.
