I don't know what Blatt was thinking in Game 5. The Cavs just don't have the personnel to go small and match the Warriors. Mozzy has probably been the Cavs 2nd best offensive option this series and Blatt sat him for pretty much all of Game 5. It was just terrible coaching but seems like he learned.
Defensively they are better when they go small. But right now Moz poses a big offensive miss match
