Moss got a rebound that led to a score by Kelenna Azubuike. Moss, 7-for-17 from 3-point range coming into the game, didn't hesitate when he made a 3-pointer with 11 minutes, 56 seconds to play to start an 11-0 Kentucky run. After twice forcing UAB misses, Moss hit another 3-pointer to cut UAB's lead to 56-55 midway through the second half.
"We just needed somebody to do something," Moss said. "We were not attacking, not being aggressive. Somebody needed to step up and I figured it might as well be me.
"I've shot well here all weekend. I've been shooting well in practice. I just wanted to take my time and hit the shots, which I did."
He played nine minutes in the second half and had six points on 2-for-2 shooting and two rebounds. His 3-point shots shifted the momentum back to UK, which had trailed by 13 points, and helped the Cats eventually take a 69-63 lead with 5:06 to play.
"What a class kid he is and he has been a tremendous asset to our program," Smith said. "He plays with such heart and determination. You could see the lift he gave us. He was the reason we were back in the game. His 3s and defensive enthusiasm were contagious."
Moss said he couldn't believe the lack of aggressiveness he saw from his teammates in the first half when UAB seemed able to dictate the game's tempo almost at will.
"I could not understand what was going on. I was watching it, but not believing it," Moss said.
"Why couldn't we get going? It was killing me. It was frustrating to sit and watch. I knew we had to step up and do something.
"This is the time of year you should be aggressive, not passive. We just didn't have it tonight for some reason. This taste won't leave us for a long time. We know this is a game we could have won."
Moss didn't think it was a case of UK's seniors - Gerald Fitch, Cliff Hawkins, Erik Daniels and Antwain Barbour - wanting to win so badly that they let it impact their play.
"These guys are veterans. They don't tighten up," Moss said. "They've played, and won, a lot of close games. For whatever reason, we just didn't have it tonight. They just played better than we did and that's why they won and we lost."
