Yeah, if PCA can run a 90 ops+ he's insanely valuable. Heck, he already has 1.2 WAR according to Baseball reference (1.4 defensive). That defensive WAR is tied for 10th in all of baseball, despite him playing 30 or more games less than the guys above him.
Dalton Varsho was worth 3.9 WAR last year while running an 84 ops+. He had 2.8 in defensive WAR. That's what I think PA'S near term potential is.
