75th Anniversary

Arkansas' U.S. Reed hits a half-court shot to lift the Razorbacks over defending champion Louisville. Moments later, Rolando Blackman drains a jumper at the buzzer to give Kansas State a victory over top-seeded Oregon State. And right after that, John Smith converts a layup as St. Joseph's stuns No. 1 DePaul. NBC's cut-around coverage allowed viewers to see all three finishes and people recognize that day as the birth of March Madness.
