There is no way people can be serious about Espinal being a better defender than Chapman at 3rd. Now if we're talking elsewhere on the diamond, no doubt Espy is better as he can also play some OF. Don't underrated the cannon of an arm that Chappy has.
Espy/Biggio seems like the perfect platoon at 2B. This is also what we said last year before Espy just severely outplayed Biggio and took that spot for most of the year. Merrifield is where it gets interesting because he's probably the better player than both lol.
