The Trojans (25-7) clipped the high-flying Ducks with their length on the perimeter and 7-footer Evan Mobley in the middle. Oregon and USC have been a big part of the Pac-12's unexpected success in the Circle City. Oregon State and UCLA already advanced, so the showdown between the Ducks and Trojans meant a Pac-12 trio in the Elite Eight. USC had to reach back to the 2006-07 team with Nick Young and Taj Gibson for its last Sweet 16 ride. USC stretched the lead to 20 in the opening 3 1/2 minutes of the second half before the Ducks finally came to life.
