Irish big man Nick George also deserves a lot of credit as he fell four assists short of a triple-double, finishing with 13 points, 10 rebounds and six helpers.
"His floor game was as good as I've ever seen it in his four years here," McClanahan said. "I thought he made great decisions with the basketball, he distributed well, he attacked when he needed to, he rebounded well on the defensive end and I'm proud of him for that."
On the other end, Catholic's 2-3 zone clogged up the middle for most of the night and left the Crusaders (8-2) settling for jump shots most of the night. Greater Beckley finished 9 for 31 from 3-point range and shot just 19 for 61 from the field.
It was the second loss in a row for Greater Beckley after it dropped its first game of the season on Saturday to Class AAA Hurricane.
"When you hit five in the first quarter and you get a lead like that, you get to pretty much dictate the game the way you want to play it, and that's pretty much what happened tonight," Greater Beckley coach Dan Burd said.
"Charleston Catholic did such a great job with [the four-corners offense] and broke us down. When we get the ball back, you've got to score quick because we're down so many points and that kind of threw us out of our offense a little bit."
Elisha Kidd scored 16 points to lead the Crusaders while Javonne Staunton Bailey added 11 and Anthony Helton 10.
Hayden McCarty got the start for the injured Patrick Herlihy and added 10 points for the Irish. Aaron Persily also contributed 10 points for Catholic.
