#3 and AB --> probably, although as someone else said, that's giving Chicago a strong backcourt for years in Dunn (assuming he develops) and AB.
Having to include #16 to get it done is where I hesitate a bit. Butler is better than AB but #3 and #16 better? I'm not so sure, especially when factoring the cost. AB developed a new aspect to his game this year by driving to the basket. if he's improved on that a bit, #3 and AB is more than enough for Butler.
