Jahlil Okafor powered Duke into the Sweet 16 stage of the college basketball playoffs. There was no such luck for a pair of No. 2 seeds in Kansas and Virginia.
Kansas lost to Wichita State in a victory for an upstart school thirsting for a shot against the Jayhawks.
Behind another steady performance from Fred VanVleet and the hot shooting of Evan Wessel, the No. 7 seed Shockers rolled past the second-seeded Jayhawks, 78-65, earning a trip to the Sweet 16 at the expense of the school that has caused them so much chagrin.
Tekele Cotton led the way with 19 points for the Shockers (30-4). VanVleet finished with 17 and Wessel hit four 3-pointers and scored 12, sending the Missouri Valley champions to Cleveland for the Midwest Regional semifinal against third-seeded Notre Dame.
And Michigan State continued its March success under coach Tom Izzo thanks to Travis Trice, who took command from the start to hand the ACC its first loss in this NCAA tournament.
