Well, yeah, when Lee ages and Fielder is in his prime, Fielder will outproduce Lee. Who's arguing otherwise? But this year, no rational person would take Fielder over Lee (for this season, discounting the age difference moving forward). I would really have a hard time taking Lee over Fielder for this season going forward. Lee's numbers are better right now, but he isn't going to hit .410 all year, and when he starts hitting .320, if he isn't hitting more home runs, Fielder will be at the worst, even with him. Well, I think you'd be mistaken to take Lee over Fielder for this season. Even without many homeruns, Lee is out-slugging Fielder .619 to .597. He has 19 extra-base hits, while Fielder has 16. I believe the homeruns will take care of themselves, but, if not, you can hit for some power without them. (Though I do agree Lee will need to increase his homerun output) But some of that slugging percentage difference is derived from some singles that Lee won't be getting all season. As long as he's hitting .410, he outslugs Fielder by 20 points, but what happens when he's hitting .330?
