What is the biggest comeback in college basketball?

The most unbelievable comeback I ever saw was the North Carolina vs. Duke game, March 2, 1974. Carolina was down by 8 points with just 17 seconds to go in the game and came back to win. And by the way, this was before there was a 3 point shot or shot clock in college.

Another incredible comeback was the little-known Barton College vs. Winona State game on March 24, 2007. That Carolina-Duke game was awesome, but Barton-Winona's was compelling on myriad levels: Barton was playing in its first national championship ever against the defending national champion, Winona, which had eliminated Barton in the Elite Eight the year before. On top of that, Barton's Anthony "Ant" Atkinson had, after being kicked off the Campbell University basketball team in 2006 for academic issues, returned to his hometown of Wilson, NC, enrolled at Barton and said he was going to win a national championship for his hometown team.

Barton trailed 74-67 with 45 seconds left. Atkinson then scored 10 points in the final 39 seconds, including the game-winning layup with one-tenth of a second left on the clock.

The comeback was nominated for an ESPY in the "Best Finish" category and named the "second best storybook ending of the past 25 years" by NCAA Champion magazine. Today Atkinson is a fan favorite with the Harlem Globetrotters.
