I was interested in this topic because of the discussion about ball movement. The team takes too many isolation possessions and doesn't move the ball enough, etc. Well the NBA actually tracks this stuff and the data is available for free on NBA.com. Looking through the stats leads some interesting results and may explain why we ISO a lot.
Player stats:

Dame uses 4.4 isolation possessions per game. He is 6th in the league behind 1. Harden, 2. Westbrook, 3. LeBron, 4. Giannis and 5. Siakam. His score frequency % on isolation possessions is 51%, far and away higher than anyone else above him (although his volume cannot match Harden, who uses 13.8 iso possessions per game, more than double second place, who is his teammate Westbrook at 6.6 possessions per game). His percentile is 90.7%, also significantly better than just about everyone above and behind him. Only Harden is close at 86.7%, but Harden may be the best isolation scorer in history at least in the regular season. Dame scores 1.16 points per possession on isos, making him probably the second best isolation scorer in the league when you take into account volume.
CJ uses 3.4 isolation possessions per game. He is 12th in the league but his efficiency is above average. He scores 1.00 points per possession, which makes him more efficient than everyone that uses more possessions than him besides Doncic, Ingram, Lillard and Harden.
Rodney Hood uses 1.4 isolation possessions per game but scores a godly 1.42 PPP. So yeah, Rodney has been good.

Unsurprisingly, the Blazers are second in the league in isolation possessions per game. However, they use half as many possessions (11) per game than the Rockets (22) who are first by a large margin. When you look at the 10 teams that use the most isolation possessions per game, you see some patterns.....Houston, Portland, Milwaukee, Lakers, Nets, Pelicans. Basically, they have guys that are incredibly good isolation scorers, and they tend to be star level players.
In terms of efficiency though, the Blazers are tied for first with Washington. 1.06 PPP puts them above Houston at 1.00, and they use twice as many possessions as Washington who also scores 1.06 PPP.
Now personally, I don't like watching isolation basketball. It's not very fun for the other guys on the floor. You can make the argument that other players play worse because they can't get into a rhythm. However the overall results paint Portland as an elite ISO team. As a whole, Portland is 9th in the league in offensive efficiency. They score about 1.08 PPP, so the 1.06 PPP is only slightly below that. 1.06 PPP would be 16th in the league in offensive efficiency if all our possessions were isolations. There are parts of their offense they can improve on but given the rotating door of players due to injury, sucking, etc....there are other more pressing issues to work on. Like defense. Our defense blows.
