Obviously, but this notion that he would be on par with Trout if he hit like him is what I took exception to. Trout is basically a league average defender in CF, if you added Trout's bat to Pillars defense you would have a 15+ WAR guy, hence the GOAT label.
Edit: I might of misinterpreted a previous post, I thought he was saying if Pillar hit like Trout they would be equal players, which would infer that their defense was on par.
