There are some things to think about here, imo. If you're going to be posting up Pau, it makes sense to have a stretch 4 in there like Niko drawing the other teams PF out of the paint. If Noah's in a C, then Pau should be hitting his mid range jumper he's so good at. It's about spacing the floor.
The problem is when you put Taj in for defense, who do you go with? Maybe a good time to play Niko at the 3 to space the floor. I really believe that Thib's hasn't figured this stuff out yet.
It's all about calling the right plays for when each lineup is in. Don't post Pau when Noah or Taj is in, etc. Keep the floor spread. Don't run Noah off the elbow when Pau is in. And please, substitute more frequently and use our front court depth more!
