"There aren't great victories unless you beat great programs," longtime Belmont coach Rick Byrd said. "... It's a big moment right now for us."
Indeed, especially considering it appeared the Bruins (3-1) would be left lamenting one that got away.
Belmont had frustrated North Carolina by playing with poise and knocking down outside shots, leading by 11 points early in the second half. Then the Tar Heels (2-1) rallied and led by eight with 2½ minutes left, only to see Mann and the Bruins push back.
With the Bruins trailing by two in the final 20 seconds, Reece Chamberlain brought the ball upcourt and flipped it to Mann, who launched the straightaway shot over Tokoto.
He said he was "about 99 percent sure it was going in" before it dropped through the net.
"It's something you dream about as a kid, and something that you pretend this summer in the gym," Mann said. "You're saying, 'All right, game winner against North Carolina, here you go.' And then it happens. It's just unbelievable."
