Even though I'm not a huge WAR guy, I think historical perspective is a decent, directional, contextual use of the stat. He never exceeded 7.3 (his number in 99). Very, very good season, but doesn't strike me as amazing in context of the time. (And, to be clear, this is not a reference to PEDs, but the watering down of pitching in context of expansion. Raw numbers are not as valuable). I think the genius of Jones, as you allude to, is the long stretch of really good play.
