With his future coach — Duke's Mike Krzyzewski — watching from the stands, Jon Scheyer put on one of the greatest shows in high school basketball history, and it still wasn't enough.

With his team, No. 1 Glenbrook North, losing by 71-58 to Proviso West in the Proviso West tournament with 1 minute, 24 seconds remaining, Scheyer scored 21 points in 1:15 seconds, the Chicago Tribune reported.

In that 75-second span, Scheyer nailed five three-pointers and six of seven free throws. He sank a 28-foot three-pointer to bring the Spartans to within 81-79 with nine seconds left, but Scheyer then fouled out trying to make his third steal during his burst.

Scheyer, 6 of 8 from three-point range and 20 of 22 from the line, finished with a tournament record 52 points, but Proviso West held on 85-79.

"I just blocked out all the shots I had missed before and played with my heart," Scheyer told the Tribune. "I wasn't even thinking. But, it wasn't enough."

Glenbrook North's streak of 35 straight victories was snapped.

Scheyer will enroll at Duke in the fall.
