I think a lot of it is his frustration at the offensive end of the floor in terms of being forced out of the paint to make room for Simmons. Taking too many 3s and longish 2s. At the same time, he doesn't seem willing to bang in the low post all game either. Too often I don't think he fights for position in the low post hard enough before he gets the ball. So if he goes up against someone who is physical with him, the entry pass to him is often too far away from the basket and he ends up settling too much for passes back out or weak jumpers. When he does try to back down his defender, he's too far away, the double comes, and he gets flustered.
All that said, I do think you have a point about Brown, but for me it's about him appeasing his players too much. They take nights off, they often play down to their competition. On the other side, they have shown the ability to up the intensity, and they do have a winning record against winning teams, and have had a difficult schedule to start. I'm not sure you want to ditch him in the middle of the season, but if the Sixers have another 2nd round exit, I wouldn't be surprised to see him go.
The on/off is the most obvious explanation: Horford is playing C during his off minutes rather than the scrub backups we've had in the past. Generally Brown correlates Simmons/Tobias/Horford together and Embiid/Richardson together, so he's penalized by the rotation a bit.
Regarding RAPM/RPM, I think it's a few things. 1 would be sample size because he was first among Cs/top 10 in the league just last week. We should start to notice more stability in a month or so. 2 his offensive skillset is less meaningful within the current roster build. Simmons needed to add the 3pt (or at least mid range) dimension to his game for our offseason to make sense, and unfortunately that hasn't happened. Sometimes Embiid is being forced out of his comfort zone, and other times he's forcing other players out of their comfort zones. Both instances occur with more regularity now. 3 he loved running the dribble handoff with JJ, so he's probably still adjusting to that not being an option.
PIPM is better than some of the other advanced metrics I've scolded, but still not something I put stock in really. I would guess the reasons are loosely related to the reasons described above, but I would need a refresher course on how it's calculated.
