I'll get flamed for this but Nash led the league's top offense in 46 of his 53 seasons.
He also shot like 93% from 3
There were very few games in Nash's prime where anyone was able to shut him down or slow down the offense he created and directed.
It's harder to consider Nash in this context because all those other guys were unguardable in a 1v1 sense. Nash obviously doesn't fit that mold but from a purely offensive perspective his peak was as good as anyone's.
