Honestly I don't think Thibs sets are horrible. I mean we ran some great sets last year with Boozer and Noah. Ran some of the double high post stuff from the Adelman Kings. Ran a few of the old Jazz sets (I honestly have no idea if Corbin still runs the same offense)

But with Rose back....everyone just stands around and waits for him to be amazing. There's not much off ball movement, guys stagnate and wait for Rose to come back and get the ball from them. Boozer doesn't post as much, or shoot as much. That's where Thibs AND the team needs to improve.
