the alltime sports rankings are usually laughable..as the 100 to 90 nba list you posted from espn is...

would be more interested in the position rankings though..

with the rules changes...basketball between different eras is so different that even position ranks are skewed

Curry is a great player in modern nba....with perimeter friendly rules....but in 80s and 90s....he'd get knocked around and flattened if he drove to the rim.
