The 6-foot-4, 200-pound Langford, who accepted a full-court pass just past halfcourt with three seconds to play, took one long stride and launched a deep three with his North team trailing, 99-97.
Kansas University signee Langford's attempt hit the rim, but didn't drop as the South held on for the all-star victory before about 4,000 fans in Dallas.
"I got the ball at halfcourt, then I took the hardest dribble I've ever taken in my life," said Langford, who hit five of a game-high 13 shots for a game-high 16 points.
"I was leaning toward the goal from 25 feet out. Our coach was screaming for a foul, but they aren't going to call a foul in that situation. The officials can't call a foul on the last shot of the game."
The 6-foot-4, 200-pound Langford -- he grabbed a team-high eight rebounds -- thought the final shot might drop.
"I had the most touches in the game. It wasn't a surprise I got the ball. Of course I wanted it. I was happy to take it," Langford said of the shot. "To tell you the truth, I didn't see it, the way the ball bounced off the rim, but my teammates told me it was close."
Just last week, Langford earned MVP honors for USA/Team Texas at the Global Games in Dallas. Langford averaged 17 points and eight rebounds as the U.S. claimed a bronze medal.
"I got a lot of experience against great competition," Langford said. "Going in, I didn't think I'd lead our team in scoring and rebounding. I wanted to win and represent the U.S. and Kansas. Hopefully I did that."
Langford -- he chose KU over Oklahoma, Cincinnati and Mississippi -- has blossomed in stature in his home state of Texas since winning MVP at the Global Games.
"I've been getting a lot more media attention here, signing some autographs," said Langford, who averaged 25.7 points, eight rebounds and four assists last year for 29-5 North Crowley High.
"A lot of people have been talking to me. I've still got a long way to go. I've done nothing yet."
Langford, who suffered a severe ankle sprain in Lawrence a month ago, says he's physically fit entering his rookie season at KU.
"I have some bumps and bruises, but the ankle is fine. It healed up," Langford said. "I'm going to take a couple of days off then get back in the gym and work out. I am hoping to accomplish some things my first year at Kansas."
