A simplified offense helped lead Chattanooga Christian School to a statement win. After struggling to get going on that side of the ball for much of the first half of the season, the Chargers switched from the wing-T to the I-formation for Friday night's key Division II-AA East Region matchup with rival Boyd Buchanan.

The response was an overwhelming success as CCS rolled to a 57-13 win behind 573 rushing yards.

"The I-formation is pretty simple, and that's what our young kids needed," said Chargers coach Mark Mariakis, whose teams had never ran anything but the wing-T before Friday. "It allowed us to put Boo Carter at tailback and be able to run him to the left or right instead of just one direction out of the wing. He's so athletic, we had to find a way to make him a weapon all over the field for us."

CCS had gained 398 rushing yards by halftime and finished the game outgaining the Buccaneers 597-203 in total offense.

Carter, a sophomore who already has SEC scholarship offers, ran for 226 yards and three touchdowns on 13 carries, most of which came in the deciding first half. Fullback Darell Brown rushed for an additional 147 yards, while twins Javoris (96 yards and a score) and Davoris Havis (74 yards and two touchdowns) were also part of the impressive night on the ground.

"We're so young," Mariakis said. "We started five freshmen and seven sophomores and still haven't used the same starting lineup in any game all season, but this really seemed to click with our guys. I think we may have found something."
