The jazz were not ranked 13th on offense and defense last year. They were ranked 6th on offense last year and 19th on defense.
This year they are ranked 13th on defense and 13th on offense up to this point. Our offense hasn't looked as good, but is off since we score more at home then on the road. But to prevent 3 less points per 100 possession on defense is a huge improvement in such a small amount of time.
