Thanks WBCD. I’ll poke around in there and learn how to use the sites. Initial take is that I Iove that the Top 4, 3 man, groups only includes 4 players.NBA.com has 3-man lineup data - both +/- and NRtg - in its statistics package.
PBP.com (https://www.pbpstats.com/lineup-subunits/nba?LineupId=1627759-1628369-1628401-201950-204001&TeamId=1610612738&Season=2023-24&SeasonType=Regular+Season&SubUnitSize=3) can give you NRtg using up to five players.
From NBA.com, here's a snip with the top +/- among BOS's 3-man lineups. Interesting that Cookies + Cream + White is the top +/-.
