EAST RUTHERFORD, N.J.—Duke coach Mike Krzyzewski called an early timeout in the second half after watching Temple outhustle his team on a loose ball.

As the team gathered around, Krzyzewski grabbed a chair, lowered his head and clinched his teeth. He banged the chair up and down a few times before asking his team, which led by 10 at that point, a question: “Where is your fight?”

Immediately, Duke doubled the lead, and Temple never threatened again as the No. 2 Blue Devils won 90-67.
