Quotes
"I definitely got going. My teammates found me, and it hyped me up, the crowd up, hyped our whole team up, and I think it helped us move into the game a little more."
– Brandon Randolph on his four 3-pointers in the second half.
 
"When someone told me on the bench, I was shocked when they said I had a double-double; I thought it was assists. As I said, it's just taking a load off of the guys: Ryan Luther, Chase (Jeter) and Ira (Lee). As a guard, that goes a long way." 
-- Brandon Williams on notching a double-double with points and rebounds.
 
"We didn't really get after them at halftime and that might be surprising. Our team doesn't have a great margin of error, especially against a team with skill and as experienced as Utah Valley. They did not catch us off guard. This wasn't a situation where we were still thinking about our UConn victory, it was just the opposite. We had excellent practices, our guys understood that Utah Valley has great size, unbelievable skill level, and they run their offense as well as any team we have faced this season. We knew we were in for a fight and it was great for us to respond the way we did at halftime."
– Coach Sean Miller on how his team responded in the second half.
