Because he doesn't operate under the typical logic of 100 pitches means I must pull the starter. He doesn't manage his pitching staff like a stupid robot, which is what RR does. Using Smith and Thornburg tonight in a blowout while tossing Wang out there last night with a one run lead makes no sense at all. Same as a couple weeks ago when he used Smith with a 5 run lead, which caused him to be unavailable the following day. The following day Kinzler blew a one run lead in the 8th.... I know we all play arm chair manager, but a lot of these decisions RR makes are failures in common sense that even a person who is not a hardcore baseball fan would question.
