Copeland is the kind of guy who provides energy off the bench, keeps everyone fired up, plays selflessly, and can sub in at PG/SG/SF. There's a lot of value there. Ideally he'd be a four year guy who, as a senior, has developed into a valuable starter.
He's not a perfect overlap with CJ Fair, but a similar concept - glue guy who plays hard, who's not selfish, with nice versatility.
Imagine Q working with a true PG and SG who can attack or make a nice pass... Or imagine working matchups in his favor, depending on the opponent. His tenacity could be very valuable in that regard.
Unfortunately right now he's either going to have to be asked to do more than he can or to make the pretty pass to someone who's going to chuck up a brick.
