You're abusing the word squarely to make it seem like he's way above average, when he isn't.
These stats are pretty much just the same as regular stats, if you look, his wOBA is pretty close to his OBP, and I already gave you that he was a plus defender. His offense is not very good, any stat you use shows he's above average, but average means you're pretty awful. FanGraphs will have him as a huge win just because he's elite defensively at his position, and he's above the average offensively.
WAR is not accurate in all situations, and for someone who keeps track of my discussions with other members, you should know I've said this more than once. WAR certainly isn't accurate in saying that Gardner was worth 25 million last year, if you think it is, you're delusional.
