Man, those two were good players too. If they were playing today, they'd be stars.
Richardson career 15, 6, 7, 2.5 steals
Lever career 14, 6, 6, 2.2 steals
I'd have to go with Lever because Richardson was plagued by cocaine use, although he was compared favorably to Magic Johnson at his best (and those comparisons actually weren't hype). Lever was probably the most consistent triple double guy in the league other than Magic for a handful of years.
How bout Terry Cummings or Anthony Mason?
