"I thought we played with a lot of effort tonight," said head coach Garry Brodhead. "I love playing here (Montagne Center). It's a great basketball arena. We shot the ball well and played with a lot of effort defensively. I think we showed up tonight ready to play."
Gordon came off the bench to lead the Cajuns with 22 points on 4-of-5 shooting from outside. Keke Veal added 13 points and a team-high five assists, while Gabby Alexander totaled 11 points and a team-high eight boards.
"The play of Keke Veal and Jaylyn Gordon was great, I thought they played extremely well at the guard position," Brodhead said.
