I don't really see the value of figuring out how valuable a position is in comparison to it being unmanned. We want to know where defensive talent can be leveraged the best, no? The way I see it, as long as SS and C are at the top and LF, RF and 1B are at the bottom, the list isn't wrong. 1B is where you put the fat old, and/or bad defenders at. There's good reason for it.
