The other question about the small sample size for Caldwell is how much he is using new parts of the playbook that teams will adjust to defend. Using the middle of the field more is successful if teams do not think you will do it. Once they get the idea that you will, they can adjust. Whether Caldwell adjusts as Playoff caliber teams do is still an open question.
Let it play out and see how things develop and who is out there and interested.
