He's certainly finally taking advantage of his players offensive strengths. The high low is very effective with Colt and RSIII, they're using DJ in the post when he has an advantage, and spreading things out when they go with DJ and Carter at the same time. Plus the guards are feeding the post more and using screens much better.
On D we're not as good on ball or pressing without Nolan but the strength we do have is length and size so the zone is taking away the inside and forcing teams to beat us shooting 3's with a hand in their face
