With 20 seconds remaining on the clock and Duke down three, Luke Kennard drove the ball into the lane looking for an open teammate to take a shot.
The ball landed in true freshman Frank Jackson's hands, who stepped into a 3, nearly avoiding the outstretched arm of a Kansas defender, to drill the game-tying score with 16 seconds left. It capped an incredible 7-0 run to draw even with Kansas.
It appeared the game might head to overtime, but another Frank had other plans. Bill Self called a timeout with under 10 seconds remaining, and drew up a play for his senior leader. Mason, who had 30 points on Friday, helped sink the top-ranked Blue Devils, pulling up from 17 feet to drain the go-ahead jump-shot with 1.9 seconds remaining. It would turn out to be the decider that knocked off Duke in a 77-75 victory in Madison Square Garden.
An instant classic.
