Yup signing Martin then was the play, I truly don't know what pills AA was hopped up on or what kind of dirt JPA had over on him then. We can only hope those ridiculous moves and shoddy evaluating turned him into the seasoned GM he's appearing to be this off season and like you said it's all coming full circle.
It's only 3 games in with him but just seeing the immediate difference in framing, defence, and gunning runners out has made me giddy as hell. Having a competent backstop can't be quantified enough for how integral it is to your overall team success (Calling games, building pitching staff confidence, defensively for the entire infield, etc.)
