He seems to be a lot better playing the hot hand. He appears to be better at rewarding good performances. His offensive sets are more fluid and dynamic than the ****fest that was Jefferson-ball. He's using time-outs better. He has just improved in many ways over the past 3 seasons, and I hope he continues to improve.
That doesn't show improvement but a change in strategy (which i thought we all expected), especially the offensive changes -- alfense was the most efficient option for the Jazz last season and going to more movement would have been the opposite of coaching improvement.
