But yeah, Merrifield, Biggio and Tapia all project to hit close to league average and it's 2 lefties and a righty so you can play the matchups some to squeeze even more value out of the bats. I think Tapia and particularly Biggio are suspect in CF but Merrifield is good enough. Combine that with the defense of JBJ and Zimmer and you've got above average production in CF.
Think about it this way, any time JBJ and Zimmer have hit for a 90 wRC+ or better (something White/Biggio/Tapia can provide) they have put up a minimum of a 2 WAR season. Sometimes much higher.
