TR missed the boat and now Span's trade value is nil. With younger, cheaper, better defenders such as Bourjos, Parra and GoGo availble this offseason via trade why give up anything for Span. Heck, Span has much better OBP than GoGo but that advantage is lost due to caught stealings and pickoffs. I like WAR for the long run but it is worthless in the short run if it says Span is +5. It needs to ind a better way of properly valuing D and accountinf for bonehead plays that cost teams outs.
