Kammeon Holsey, who had 10 points, missed the first of two free throws early in the second half to leave the Yellow Jackets 0 for 7 from the line, but he made the second attempt, bringing a loud cheer from the crowd. Overall, Georgia Tech made only 4 of 11 free throws.
"We're just not at a point right now unfortunately to be good enough to make up for some of the glaring mistakes that we made," Gregory said. "Turnovers and empty possessions. If you get to the foul line but miss the shot, it's just as good as a turnover."
Hairston, who made only 4 of 15 shots, finished with 10 points.
Among the former Georgia Tech stars in the stands for the game: coach Bobby Cremins, Miami Heat forward Chris Bosh, Atlanta Hawks guard Anthony Morrow and Detroit Lions wide receiver Calvin Johnson.
