if one were to put some thought into it, one could extrapolate that since team UZR does, in fact, have a positive relationship with lowering ERA, that individual UZR could, in fact, have a similar relationship. like i said, i understand that there is a lot of truth in uzr. i never said there wasn't. i'm saying it's unreliable and shouldn't be used to judge performance by a player and then act like it is definitive at all. according to uzr, derek jeter has become one of the best defensive shortstops in the league the last 2 seasons after being horrible for 3 straight years prior to that. so are the numbers inaccurate, or has jeter suddenly become a great shortstop? i think the former seems more likely.
