Coach Tony Barbee's team is now 2-5 in SEC play and 8-12 overall while Georgia improved to 9-11 overall and 3-4 in the conference.
"You shoot 28 percent you are not beating anybody," Barbee said. "You aren't beating anybody at home, you aren't beating anybody on the road.
"I don't think we executed very well, we were sloppy in our execution," Barbee said. "We didn't turn it over much, but we didn't execute it like we normally do so we didn't get the kind of looks we wanted. Then 15-27 from the (foul) line isn't going to cut it.
"Defensively, I didn't think we were very good either," Barbee said. "Georgia got just about whatever they wanted. They had their players step up and make plays when the game was on the line. We weren't able to."
