Weeks had a nice five year stretch from 2007-11 where he posted 12.8 WAR over 2,497 PAs. Problem was in his other six seasons he put up -0.4 WAR over 2,203 PAs, with the main thing holding his value back being his abysmal defense, -115 DRS. The next worst DRS among 2B since they started tracking it is Daniel Murphy at -68. For his Brewer career BRef has Rickie at +57 BAT | +26 BSR | -115 FLD | +28 POS. Even with the positive positional adjustment for playing 2B, Weeks still gave back all his offensive value when he was in the field. Compare that to Gantner who had a five year stretch from 1979-83 where he posted 11.9 WAR over 2,235 PAs. Pretty even peak with Weeks. Difference is Gumby posted another 10.5 WAR over his other twelve seasons & 4,552 PAs, closing any gap & then some. I guess if you want to ignore defense & longevity, sure, Weeks is the best 2B the Crew ever had.
