Armed with a polished all-around game but no clear go-to move, he overcame a slow start to his freshman year with some clutch late-game shooting and a 40-point showing against Clemson in the ACC tournament. He seemed more prepared to handle the expectations as a sophomore, but was dominant only in stretches and faded badly late in the year.
Barnes averaged 14 points on 36 percent shooting in the last 10 games. He shot a combined 8-for-30 overall and 2 for 14 from 3-point range in his final two games without Marshall.
The departures mean Reggie Bullock will be the leading returning scorer at about nine points per game for what likely will be a guard-heavy lineup. Dexter Strickland and Leslie McDonald are both expected back from knee injuries along with P.J. Hairston, who struggled with his outside shot through his freshman year.
Ronnie McAdoo, the father of freshman forward James Michael McAdoo, said his son plans to return to school but will review his NBA options with the family this weekend.
North Carolina also has a recruiting class that includes likely Marshall successor Marcus Paige, a McDonald's All-American from Marion, Iowa.
