Teams would rather pitcher to Dye than Cameron with Fielder on base because Dye gets out more than Cameron. It doesn't help to talk down to the audience here. The people here not only understand baseball, but they also understand very simple mathmatical concepts, something you don't seem willing to grasp. I'm not intending to talk down to the audience, and if that is what you are recommending I do, then I suggest you do the same. I understand mathematical concepts, I just find the lack of balance in discussion frustrating. I think it's premature to use any one measure to determine a player's value to his team, and there are definitely inadequacies to be found in WAR's calculations. Teams would rather pitch to Dye than Cameron if you are simply talking about OBP, but I think it goes beyond that, as in Dye is a more dangerous hitter and strikes out less. I think most managers would take more into consideration than just OBP.
