“I feel like I just played off the flow of the game,” said Mobley, who was named tournament MVP. “I feel like they had smaller defenders on me so I knew I could get it down low. My teammates believe in me, the coaches as well, to just to put me in a position to score. It wasn’t pretty, but we got it done.”
Trey Pulliam scored 11 points, while Lamont Butler and Aguek Arop each had nine for San Diego State (4-2), which was held to its lowest-scoring opening half since 14 points against Air Force on Jan. 12, 2019.

“That was a very good defensive team. We’re a good defensive team so I recognize when we play against one,” San Diego State coach Brian Dutcher said. “You grow from winning, you grow from losing and now unfortunately we have to grow from a loss.”
Peterson not only was 6 of 10 from the field for the Trojans, he helped hold SDSU leading scorer Matt Bradley to three points on 1-of-7 shooting.
“We used to spell Drew R-E-W. There was no D in his game so we called him Rew Peterson,” USC coach Andy Enfield joked, earning a chuckle from Peterson, who was sitting next to him. “Now we call him Drew because … he’s learned how to use his length, he’s learned how to anticipate drives, close down and challenge shots.”
