N.B.: Denny Lyons, who is not in the Hall of Fame, was a nineteenth century player whose best years were in the inferior American Association and whose career ended at 31; he’s not really part of the conversation.

You can make an argument that Chipper’s the best third baseman of all time. If he plays 100 games or more, he will probably move past Eddie for the most RCAA all time in 2009; 26 behind, he has had more than that every year of his career but two (1995 and 2004). He has had at least 84 runs created every year of his career; that would move him up to second behind Brett. And his per game numbers are so much better than Schmidt’s that even a relatively steep decline would keep him the modern leader in RC/per game.
