I missed this until it was discussed in a more recent article. Jeff Zimmerman has re-calculated Tom Tango's positional adjustments, and his numbers look a fair bit different than Tango's, with DH and 1B being particularly undervalued, maybe. Oakland's Billy Butler signing probably reflects internal work with a similar conclusion. I wonder if fangraphs will end up adjusting their fWAR.
Greenwood: this would be an appropriate time for you to talk about Colabello.
