I agree that Devers should be playing mostly every day. Xander needs some time on the DL, IMO, but if he truly is healthy, as Farrell maintains, then benching him is not the answer.
As far as the line up goes, a shake up might help to get some guys going, but outside of that, it doesn't make much of a difference. You can set the line up any way you want. If the guys aren't hitting, it won't matter.
