Leesville handled winless Grant on both sides of the ball to remain perfect on the season.
The Wampus Cats scored two defensive touchdowns in the 41-8 victory Friday night on the road.
"I thought, defensively, we ran to the football, and on offense, we made plays when we needed to make them," Leesville head coach Robert Causey said. "It was hard to get into a rhythm. We did what we are supposed to do against a team like that. You get back on the bus and get ready for the next week."
Gaining a big lead at halftime allowed Causey and his staff to play the younger players and avoid injuries as they head into the final stretch of the season.
"We wanted to do our jobs and see how the young kids could handle those types of expectations," Causey said. "It was all mental. Football is more of a mental sport than it is a physical sport. We took care of business. It was one of the weeks where you are better than your opponent, and you try to come home without any injuries and get ready for the next week."
The Wampus Cats opened up the game with a 57-yard touchdown by Caleb Gallashaw and followed it up with a 65-yard pass from quarterback Jacob Mount to tight end Khrystian Hoffpauir to go up 14-0.
Nigel McCoy recovered a fumble and ran it for a score to give Leesville the 21-0 lead at the end of the first.
"Our first and second huddles played well," Causey said about his defense. "I thought we swarmed to the football in both of our huddles. They just played with relentless effort."
In the second quarter, Mount hit running back Darrius Sawyer for a 50-yard touchdown, and Christian Person intercepted a pass for a 20-yard pick-6 to make it a 35-0 lead at halftime.
In the third quarter, Mount connected with Sawyer, once again, for a 77-yard touchdown for the Wampus Cats final score.
Leesville takes on rival DeRidder for the Hooper Trophy next week, followed by a matchup with Tioga.
"We are where we are. No matter if we're ready, it's still coming," Causey said. "We have had to replace so many players and have so many first-year guys that are playing right now. I think where we are at is where we need to be. It's now about if we can finish. Every week is a playoff atmosphere and has playoff implications. It starts now with that mentality and how you prepare."
