I dunno, hard to say. A few years ago I would have said he was likely on track to be a HOFer, but he's aged fast. Not all that uncommon for catchers, but it's caught Yadier even earlier than most.
Even so, he has been the best defensive catcher of the past decade by a comfortable margin. He has been great at everything - game calling, pitch framing, throwing, on-field leadership, all of it. At this point, I don't see him quite getting there. But he's close.
