See I took player analysis as also including analysis of their tendencies. I doubt there are many multi-variable regressions in which RBIs are valuable, but I wouldn't exclude the stat completely. It may be a quick and dirty window into a deeper issue in some situations. But neither of us know what the Twins are or are not doing in order to analyze their players, I just hope they aren't artificially restricting their analysis because something is seen as antiquated. (Or, worse yet, not antiquated enough)
