At 37 years and 65 days, Steve Nash is the oldest assists leader ever.

However, it also looks like he's the oldest leader for *any* of the major statistical categories.  I know Rodman, for example, was slightly younger than Steve when he last led the league in rebounding (during his last year in Chicago), but I'm stumped at finding any other geezerly players who might also have led the league in other categories.

Just wondering if y'all could confirm this, or help find the counterexamples.
