I'm enjoying reading this conversation - I think there are good points for both sides of the argument. I think WAR is an interesting stat to look at in hindsight, but I agree with the criticism that taking less than accurate defensive metrics and lumping them into the equation is problematic. The last couple MVP debates have used WAR a lot to compare Miggy and Mike Trout. Trout gets a boost for playing CF (which, ya know, I think he should , at least a little bit) and Cabrera just hit and hit and hit - Average, power, and took advantage of his teammates being on base in front of him. The career WAR stat is kind of hard to rely upon as well - It's not recalculated, is it? It looks like they take each season WAR and just called the sum the career WAR. If the Defensive metrics have to be adjusted over the years . . . Wouldn't the "Career" WAR need to be a different math problem than simple addition? What about a guy like Biggio or Yount, who played in CF for chunks (but not all) of their career, compared to Edgar Martinez or Big Papi, who get no defensive boost - can't really compare the Career WAR of those players. Or Joe Mauer, who now has to be a different hitter entirely to be a 5 WAR player since he's not getting the benefit of doing what he does as a Catcher anymore. I think that stats are cool. WAR really only compares a player to his own shadow, and not really to another real player. You can make the argument that a 10+ WAR season like Mickey Mantle in the 50's or Babe Ruth or Barry Bonds is better than pretty much anyone else. But if there are two players, say one with a season WAR of 5.3 and another with a season WAR of 4.9, it's going to be harder to say that 5.3 is for certain the better player that year. There's a lot more to account for, including a margin of error for the defensive portion, what position the guy plays, etc. etc.
