Oleh has already noted that the New Orleans Pelicans continue to lack a real answer at small forward. In digging through draft profiles on Draft Express (which you should do if you have the time) two candidates stood out to me as possible answers to the small forward question. The Pelicans require size, length, and some competency shooting the 3-point shot. Al-Farouq Aminu clearly demonstrated the limitations when one of those ingredients (shooting) is missing.
Tangent: Yes, Aminu was much more successful playing "small forward" in Dallas. This is largely because he could function as a power forward on offense when surrounded by known shooting threats like Dirk Nowitzki and Chandler Parsons.
