I prefer (x) for negative . . .
Blue has a point. They made one defensive upgrade going into last year, Kotchman for Branyan. The other intended infield moves were downgrades - Lopez for Beltre and Figgins for Lopez. The Figgins signing was to replace Beltre's offense, not his defense. From '07 - '09, Figgins had a higher average, OBP, walk to stirkeout ratio, and, for 2 of three years, wOBA (darn new fangled stat). That move was to upgrade the offense at the expense of defense. The Kotchman move was not just about defense, either. Kotchman was also younger (Branyan had some injury issues in '09) and had been highly regarded through '07/ '08. He was a year or so from being traded for Mark Teixeira. The difference in defense from '09 to '10 was a heck of a lot less than the upgrades from '08 to '09. Don't hear much snark about what they did then or how they went from 2d worse record to near the playoffs.
