Russell's advanced stats have to be suspect because they didn't count steals or blocks until 74, right?
On the Big O debate, I think it's worth looking at his playoff career before the Bucks got Kareem. Oscar freely admitted he didn't view it to be "his job" to play defense: "that's why we have all these other guys." He and Jerry Lucas, Jack Twyman, Happy Hairston, Bob Boozer...they should have been better than a 45 wins/first round playoffs out if Oscar was so all-time.
Great player but I'm not sure I'd put him above Jerry West (elite defender in addition to his scoring) for the best guard of the 1960s, never mind on a Mt Rushmore. My preference will always be for great two way players.
