Cons:
Slow laterally, and is awful w pick and roll D. His D since the trade has looked worse to me via the eye test.
One of the streakiest shooters I have ever seen. Last year he was awful the first part of the year and looked great in the second half. I've watched him play in probably 30-40 games over the last couple seasons (I usually have 3 screens on in the evening). He can be aggravating how inconsistent he is on both sides of the floor. I watched the Bulls try to use him as a focal point moving him into the starting lineup, and watched him wilt and the offense slowly move away from him relegating him to spot up shooting, which again, has been inconsistent.
Low BBIQ. He takes bad shots. Lots of 3s way beyond the line, etc. Can't figure out defensive schemes. Gets beat by the same thing over and over...
Under contract for another year. Either give up assets or wait to get him.
If the Jazz can get him to shoot consistently (big if) he could be great sort of like Memo. The thing I've noticed about Favors, is how well he guards smaller players on the pick and roll. Not elite by any means, but he gets slow and stays in front of guys, and contests on shots. Mirotic definitely can't do that.
