This is the first in a two-part series I'm doing using different stats to see just how overrated some "run producers" are by their RBI numbers. It takes its inspiration from Jonah Keri's piece in Baseball Between the Numbers, but uses different (and better) stats -- wOBA/linear weights rather than MLV/VORP. I have some links to some nice "leaderboards" that I put on Google Docs. Next week, I'll revisit the topic using some of FanGraphs more contexual stats.
