(I don't think you need to be a subscriber to see that article.) Tim Malone looks at how much WARP (= WAR) GM's have gained and lost through trade, and at what cost. Figure 1 is the most interesting, showing net WARP per year and net WARP/$ per year. The bad news is Zduriencik's bad on both; the 'good' news is that you'd have to expand both axes by a factor of four to find Bavasi in the bottom-left corner, so comparatively Z looks great.
