Via BTB. The Rangers have lost 60.8 WAR since 2006 (The JD era) -- the biggest loss of any team. The methodology is a little flawed, but it's still pretty fun to look at and think about. I'm not sure if the author is continuing to count the accumulative WAR of a player who has signed a new contract since being traded or not. But in a very boring offseason, it's something to talk about.
At the risk of flogging a dead horse: Over one-third of that lost WAR comes from the Adrian Gonzales trade. A-Gon, who was traded during the 2005-2006 offseason, accounts for 22.7 WAR. Chris Young, who was also involved in that trade, accounts for 4.7 WAR since 2006. Terrmel Sledge is the only piece that Texas gave up who accounted for negative WAR, -0.3. Overall, that's 27.1 WAR that was traded away. Adam Eaton gave the Rangers a whopping 0.6, making for a total loss of 26.5 WAR.
So, to answer JD's question from Newberg night: yes, you are still the guy who traded Adrian Gonzales.
