Duke was down 70-51 with 14:26 left to play in the game - and the Duke reserves sparked a whirlwind comeback that only took seven minutes.
After explaining how the team came back to win, Krzyzewski was also asked about sexual assault allegations against a former Blue Devils player.
Duke used a combination of hot shooting (10-of-17 from the floor over that stretch) and dominant defense (Louisville was just 2-of-10 over that same stretch and committed 13 second-half turnovers) to steal a game they had absolutely no business winning for the first 30 minutes. It was a little frustrating at first. And shout out to Jordan Goldwire. "He really stepped up for us". Williamson and RJ Barrett got aggressive, and started attacking Louisville's defenders in one-on-one opportunities.
It was the second-biggest second-half comeback in Duke history.
By halftime, only Williamson had made a significant impact for the Blue Devils.
In addition to showing off his Monstar strength, Williamson went off for a game-high 27 points to go along with 12 rebounds as the Blue Devils overcame a 59-36 deficit with under 10 minutes to play. The fact that the Blue Devils pulled off this comeback at an ACC rival in Louisville, with the Duke starting lineup featuring four freshmen, is simply remarkable.
Earlier, Reddish tied the game 69-69 with a clutch three-pointer with 1:16 left on the clock.
If you add that performance to what the Blue Devils have already done this season, they have to be considered the front-runners to win the national championship, despite Tennessee actually being the No. 1 team for the last month. While the Cardinals couldn't find any kind of rhythm or organization on offense, Chris Mack was left to look frustrated on the sidelines with few ways to rally the troops.
The win improved No. 2 Duke's record to 22-2.
This comeback was an incredibly gutty performance from Duke and would have been historic even if it came against a cupcake school out of conference.
