Harrison Barnes, once the No. 1 high school recruit in the nation, was a presumed eventual No. 1 overall NBA Draft pick when he joined North Carolina. Sensing that he hadn't reached those heights quite yet last season, he returned for his sophomore year. Barnes was very solid, but slightly disappointing for the second straight year as a sophomore, but has decided that the time is right to test the NBA waters.
Barnes could go as high as No. 2 overall, but he's likely to drop a bit, to the edge of the top-five. He has the offensive polish to be an elite NBA scorer, but his numbers don't quite match up with his raw skills.
It would be surprising if Barnes didn't end up as a very reliable scorer in the NBA, but based on his production in college, teams in the top five might look past him and take a guy they think has less polish, but a higher ceiling.
