simply false. The warriors with KD would run over every team you have listed. Small ball is still a strength, it’s just less obvious now. It’s not even small ball actually. It’s purely 3 point shooters. If you could have normal size guys that shot the 3 as well as 6’3 guys, we’d have no small ball. The thing is, the distribution of height will never change, so running small ball will always be more effective.
