Despite his solid wRC+ it’s disingenuous to say his hitting is only down a little. His OPS of .732 is well below what he did last season and also quite a bit lower than his career .792 OPS. His BABIP is actually higher than his career average and strikeout rate is way up. So he hasn’t been unlucky to this point. If anything he’s been lucky to hold his current OPS.
Also, not sure how his fWAR is holding up because his framing has been ordinary this season.
It’s ok to admit he’s been a disappointment so far this season. I hope he turns it on soon in this weird season because historically he has performed poorly late in the regular season and terribly in the postseason.
