I agree, Chicago probably won't let him go. I am hopeful re: Smart, too. He is young, but if the offense develops alongside the defense, we could definitely have a solid starter that can help shape a strong locker-room culture.
Edit: Just watched highlights from Boogie's game against Pelicans last month - 24, 20, 13, 4... wow. Not sold that we have enough to land him, but wow..
