As for Barnes being a very good defender, see
2. Sophomore small forward Harrison Barnes, who was a middle-of-the-pack defender last season, has regressed to the point that he has the worst stop percentage of any rotation player (50.6). He's allowing opponents to shoot 49.0 percent on three-point attempts, and his defensive rebounding percentage has dropped from 12.6 as a freshman to a non-factor-level 7.4. Barnes needs to be a more engaged defender if he plans on leading UNC to a national championship.
What do your eyes tell you when you watch Barnes play D? I see a guy who has very good lateral quicks and has no problem staying in front of his man.
