Gose has a 1 WAR in 227 plate appearances and .345 OBP against RHP. His defense and speed alone should make him a valuable player, maybe a 2 win player over a full season if he maintains his walk rate. That's valuable.
Pillar is more questionable. He seems like he might be an overachiever type, but starting him in left when his best role is probably at CF against LHP only is questionable.
The defense is way better with Gose, Pillar, and Goins starting. That's really the only positive I can think of.
