Looks like Juju is questionable but expected to play, though he was held out of practice Wednesday and Thursday. If he's limited, that might tilt the scales in Diontae's favor.
I'm not too worried about Gallup being inactive, barring a major setback, but he could also be a bit limited in his first action.
So do what you want, but just be prepared to face the Unbending First Law of Fantasy Football--no matter who you start, it will be wrong.
