They aren't even trying to get other people shots. They are literally trying to get Dalton the ball every time. It's costed them. Other guys like JJJ, as you said, and Gainey had decent games going.
The only person on their team that's a bad matchup is Edey. They won the last time because they went to the free-throw line 48 times. I actually think Tennessee is a bad matchup for them.
