SAN ANTONIO — Three keys to the Duke-Houston Final Four clash on Saturday:

Duke hasn’t trailed yet in the second half of this NCAA Tournament.

It has faced very little game pressure. A strong first half could go a long way to an upset.

Remember, the Blue Devils are led by fantastic freshmen Cooper Flagg, Kon Knueppel and Khaman Maluach who have been able to play free and loose because of the one-sided nature of their victories.
