By putting the ball on the ground, Brentwood put the game out of reach of Gallatin on Friday night and claimed a 41-6 win.
With the offense clicking after halftime, the Bruins (6-0), ranked No. 9 in Class 6A, handed Gallatin (2-4) its third consecutive loss while picking up momentum heading into next week's showdown against Centennial.
Senior Ben Green led a powerful Brentwood rushing attack with 166 yards on 22 carries. He ran for 116 yards in the second half.
"We had a rough start and a rough first half," said Green, who has 663 rushing yards on the season. "We just decided to go back to the basics in the second half and start running. No matter what happened in the first half, I knew our team was good enough to do that."
Brentwood finished with 365 total yards, including 305 rushing.
Gallatin, which was without starting quarterback Morgan Campbell (shoulder injury), stayed close in the first half and trailed 13-6.
After throwing eight passes in the first half, Brentwood opened the second half by running on 27 consecutive plays. The Bruins piled up 151 yards and 11 first downs on their first two drives.
Brentwood took a 20-6 lead on a 1-yard sneak by Aaron Maher in the third quarter.
It stretched the lead to 27-6 on its first pass of the second half, a 5-yard toss from Maher to his cousin Jack Maher in the fourth quarter.
It was Brentwood's only pass in the second half.
Brentwood added two more TDs in the final 5:59.
The Bruins scored on all four of their possessions in the second half. Gallatin did not cross the 50-yard line in the second half.
The Green Wave finished with 79 total offensive yards and four first downs.
Sophomore quarterback Julian Meador, who replaced Campbell, completed sixof 13 passes for 41 yards and an interception.
"Not having (Campbell) changed a little bit of what we wanted to do offensively," Gallatin coach Mark Williams said. "But all in all we've still got to block, still got to tackle and still got to play well on special teams. We were doing good things in the first half; running around, flying around the football and making some positive things happen on defense. The defense definitely was the field a lot tonight. It was way too much."
