Just being a homer here, but for SS, Crawford has higher fielding, batting, on base, and slugging averages.
Story (COL) looks good, too, with 60 RBIs, 21 ahead of the next SS, with a strong fielding percentage. Yeah, he plays in Colorado, but 50% more RBIs than the next guy? That's pretty impressive.
Freeman (ATL) seems to be the guy at 1B: he's crushing it at the plate (tops in every hitting percentage except OBP, where he's second, second in RBIs, third in HRs), and respectably near the top in fielding (where all the 1Bs are pretty high).
