And here is Kapler about his best defensive IF (in a Gelb article at the Athletic):
"“I think it’s Scott at shortstop and J.P. at third base,” Kapler said. “I think that covers the most ground. It’s very close, right? When you put J.P. at short and Scott at third base, that would be a pretty good defense as well. I don’t know if there’s a huge difference either way. But I’m very comfortable with the developing shortstop in Scott Kingery and a very good athletic third baseman in J.P. Crawford.”"
