RBI is not meaningless. When it comes to evaluating an individual player's performance, yes, it pretty much is. So if there was a player the Cubs acquired who had 125 RBI last season, you wouldn't think that would be meanginful? Nope. You can't really tell much from that. It's almost tantamount to acquiring Sean Estes after 04 because he won 15 games. It's a stat that's extremely dependent on the rest of the team and a good amount of luck as well. Should the Dodgers have signed Pierre to that contract last year because he got to the ever-meaningful 200 hit total last year? EDIT - I realize that the Pierre stat is, however, not a team-dependent stat, but it shares the flaw that it's a counting stat and not a rate stat, and one that doesn't say a lot about a player but that people put a whole lot of stock into.
