Ben Smith's 30 points led Jacksonville, which went on a 33-13 run to trail 77-74 with 40.8 seconds remaining, but his effort wasn't enough to keep the Dolphins (0-5) from avoiding their worst start since 1996-97.
But the Yellow Jackets' (4-0) free-throw shooting nearly buried them. Ranked 312th before the game with a 59.0 percentage from the line, Georgia Tech hit just 7 of 14 in the final 1:21.
Despite Jacksonville's struggles this season, the Dolphins continued a trend of staying close late in the game, but they now have lost at Baylor, No. 22 Georgetown and Georgia Tech by a 7.2 average.
