Not to start an arguement here (I agree that Pujols has been and probably will be the better player), but I don't think FPCT, RF and ZR are good statistics for judging first basemen. Lee's RF is low because he has played on teams that have pitchers who strike out a large number of batters. Those statistics also neglect the fact that Lee is one of the best in the business at digging out balls in the dirt and is fantastic at making the play to second base. Pujols is a good first baseman defensively, but I don't see how you can rate him above Lee. You're right about FPCT and RF not being super important for first baseman. Still, they are some available criteria we can use to compare players. ZR is a better statistic in this case. I do not assert that Pujols is a better first baseman than Lee. What I am saying is that Lee is not that much better than Pujols. Fans who watch Pujols play first every day see that he digs balls out of the dirt with the best of them, and that he has a very good infield arm and can make great throws to any base at the right times. This is only Pujols' second year playing first so he is still imrpoving at the position. I know this sounds like sheer homerism to Cubs fans, but Pujols may well win a gold glove at 1st some day, and not because of his offense. Pujols is a better player than Lee, no doubt of that. But I will say that Pujols isn't, and barring catatstrophic injury, never will be a better defender than Lee.
