Says SI.com:

24.  SIXERS: CAMERON JOHNSON, SF, NORTH CAROLINA

Height: 6-8 | Weight: 210 | Senior

At this point, Johnson looks like one of the more NBA-ready wings available, with a potentially elite catch and shoot profile that makes him a good first-round bet despite his advanced age and history of leg injuries.

He’ll only be average defensively, but his touch and mechanics are for real, and Johnson will have to be accounted for on the floor at all times.

A playoff team like the Sixers might be able to use him immediately as a plug-and-play floor spacer.
