For Bulls, signing Hollis-Jefferson could add a vet off the bench who could score and defend with his addition the bulls bench might be good enough to compete against other bench.
For OKC, a 22-year old F could be also a good piece of the future and honestly I like how troy brown plays and he also have a lot of potential and I think to be with a team full of young players he could improve out their and be a solid bench player in the future but in return they need to give up a 2nd rounder.
