But Lawton came up empty on a 15-play drive that took up nearly half of the fourth.
Southmoore picked up four first downs on the next drive, although the final play of the drive gave Brickman the most heartburn.
The SaberCats' No. 1 punter was hurt, and Brickman didn't want to risk another bad snap on a punt like the one that had cost Southmoore a safety early.
He also didn't want to send his offense out and have Lawton get the ball at around the 40.
So Brickman ordered a quick kick, resulting in a touchback.
Still, the SaberCats forced Lawton to the air with Meservy, who started after Dallas Sealey was injured last week.
Lawton picked up one first down on a penalty but couldn't move it any further as Southmoore closed out its biggest win of the season.
“I had some opportunities when Coach (Chris) Jensen left to do some different things,” said Brickman, who was an assistant before Jensen left to become head coach at Oklahoma Baptist University. “I really wanted this job because I believe we had a special team. I put so much work into the last few years, and I wanted to be a part of it.
“I'm so happy that they're doing well. Let's just not stop here. We've got a big game next week. I think we can win the gold ball, I really do. Especially with the way our defense is playing. The defense won this game for us tonight.”
