↑ This website isn't exactly "advanced" stats, but the Game Flow tables are extremely useful to look at to see what lineups are on the floor during any part of any game, and to see how the game went when a player you are interested in was playing with certain teammates and playing against other players. And the Box Score tables include a Productivity score, similar to PER, where you can quickly check individual players productivity while he was on the floor for specific games.
Usually the games are updated early every morning following the games the night before. But for some reason, the last games I see updated this morning are for Nov 30, 2022. Today is a few days later --- Dec 3, 2022. Hopefully the website manager is just out on vacation and will resume updating the games every morning.
