If those are the only stats you're better off assuming that player B was on a better team. :shock: Or, if I were to look at the history of those players RBI per year, I could determine that player B was a consistent run producer, and player A wasn't. If you're only looking at RBI's per player each year? That wouldn't be a safe assumption at all. Sure, that COULD be the case, but there's much better and more accurate ways to determine whether or not a player produces with people on base than only looking at RBI totals. RBI's hinge too much on the performance of the players ahead of that hitter to be an effective stat on their own in evaluating how well he hits with guys on base. A low total in RBI's could very easily be reflective of a player who is an excellent hitter and very good at driving in runners but is on a team where the players ahead of him are awful and he's up to bat too often with nobody on or in scoring position. 2005 Derrek Lee is a primo example of this.
