"Garret is a great point guard," McClanahan said. "He is continuing to learn the game and develop his skills. He has another gear that he is going to find, too. He's an excellent player."
McCarty was glad to get off to a hot start, hitting his first three shots, all 3-pointers, in giving his team an early lead. Catholic never trailed despite several pushes by the Bison.
"It got my confidence up and my team's," McCarty said. "I'm shooting the ball well right now. It really relaxed us. Everyone was a little nervous. This was a big game for us."
McCarty averages a team-high 20.5 points per game. He and George account for 75 percent of Catholic's scoring.
With Patrick Herlihy - the team's third-leading scorer at around 11 points per game currently injured - the Irish are looking for another scorer to complement McCarty and George.
Catholic got a solid game on Wednesday night out of Aaron Persily, who tallied more than half of his season average with 12 points.
"Aaron has been huge," George said. "He's been consistent and a nice presence inside. He's been very helpful throughout the season and those 10-12 points is really huge for us."
Despite trailing all game, Buffalo wouldn't go away quietly. After giving up the first nine points of the game, the Bison cut it down to five late in the quarter.
The Bison trailed by 13 at halftime but trimmed the lead all the way down to 54-50 late in the third quarter before George's fortunate rolls finally ended any hope of a comeback.
"Our guys played really hard," Buffalo coach Chuck Elkins said. "We were close but no cigar. We just couldn't get over the hump. When we do, we will go from average to being good."
Isaiah Robinson led Buffalo with 20 points and Laythen Good added 16 points.
