WTM interprets some great information from Bill James about over-managing, platoon splits, taking the extra base and preventing stolen bases. There's a ton of interesting bits in the article, such as the following:
-Jim Tracy takes advantage of platoons, which is a good thing.
-Craig Wilson is probably not a particularly bad baserunner; Daryle Ward and Sean Casey are horrendous.
-Rick White was terrible last year at holding runners; Dave Williams and Zach Duke were great at it.
