Really really hate this. So why'd we bring him back, if that spot in the offense is just a ghost slot anyway? The whole thesis behind Barnes was he was an elite offensive role player that got to the line at an elite level with great wing spacing. And he's never been a good defender in a Kings uni, but he's always been passable.
That defense is long gone though and I think part of the reason he's disappeared on O is he doesn't have the same juice to attack the basket and get to the FT line. So he's basically a small-ball 4 spacer that can't move his feet on defense. Oof.
