Buffalo (6-3) was limited to just 16-for-46 shooting from the floor and looked out of sync from the get-go.
"It was a classic case of not showing up," Bison coach Chuck Elkins said. "We failed to show up in the first half. In the second half we shot a little better but we shot terrible all night. I honestly don't think we were ready to play. We played a good game [Thursday] night and I won't take anything from Valley, they've got a good, solid basketball team, but we didn't play well."
While Valley's inside duo racked up points and rebounds, senior wing player Raeshawn Breckenridge was finding other ways to affect the game.
He scored just eight points on only eight shots and instead turned into a distributor, recording seven assists to go with nine rebounds, four steals and two blocks.
"He's our leader," McCoy said. "He just makes plays for us. We've got to put the ball in his hands because he makes things happen. He'll penetrate and he dishes off to others - it's a well-rounded team. We feel good right now, we've just got to keep it up."
Buffalo was left without a double-digit scorer with John Hodges leading the way with nine points.
Starter Bradley Harris was in foul trouble all evening, and after getting hit with three in the first half was ejected just 1:33 into the third quarter after being called on a blocking foul and a technical foul immediately after.
Corey Hoshor and Isaiah Robinson each added eight points for Buffalo.
