The likely 2021 NBA Draft lottery pick has one double-double, a 13-point, 11-rebound effort against Santa Clara on Feb. 25.

He is connecting on 56.1 percent of his field goals, including 38.5 percent from 3-point range, and 80.4 percent from the free throw line. He is coming off a 13-point, eight-rebound effort against Creighton in the Sweet 16 on Sunday. He has recorded four double-doubles and one triple-double this season, including a 12-point, 13-rebound, 14-assist performance at Portland on Jan. 9.

Why USC can cover

Freshman forward Evan Mobley has helped power the Trojans, averaging 16.3 points, 8.8 rebounds, 2.4 assists and three blocks per game. Four other players are averaging 7.7 points per game or more.
