What happened? A diagnosis

The overall perceptive was that Luka and Kyrie are not great defenders, which is totally true. But, it was not Luka and Kyrie that were cooked for most of the game with Indy. It was a simple Haly-Turner PnR for most of the plays, guarded by Green and center and Mavs were just clueless. Only late in the second half Luka was exposed a couple of times, when he was already visibly frustrated with how the game was going. It is not the teams are attacking Luka and Kyrie, the overall scheme just doesn't work.

True, Mavs don't have any all NBA defender on the squad and this is definitely missing. But, someone needs to take accountability. Whatever player changes they make, the schemes are just not working. So it might be easier to try different schemes.
