Range factor and zone rating don't tell about range, just plays made. You need to look at OOZ plays to get a good idea of how encompassing a players' range actually is. Weeks had 41 OOZ plays in 1056 innings. The players who had more OOZ plays: Utley (the modern ideal player) 66, Lopez 51 in 1229 innings, Uggla 45 in 1272 innings, Iwamura 44 in 1337 innings, and Roberts 42 in 1320 innings. To me this says Weeks has really good range.
