JD was able to accumulate 5.9 WAR despite the negative dWAR. In other words, he was that good at what he did offensively. As I said earlier, Mookie and Trout were in a class above the rest, but if those two were not in the picture, my vote would be for JD. He was signed for his offense, and his offense was better than the rest of the WAR leaders beyond Mookie and Trout.
