The contest between the two 6A powers turned into a back and forth affair with each team putting together solid streaks.
The Bulldogs got on the board first and raced out to a 14-0 lead only to see Petal storm back with 21 unanswered points.
With the teams tied, Petal had a chance to retake the lead, but Adams took matters in to his own hands, literally.
On 3rd and long, Adams drove his man into the backfield, used a spin move to free himself and then sacked the quarterback.
"He dropped back and my man tried to use his hands to keep me on the outside, so I went inside," said Adams. "I just had to step up and make a big play."
Stepping up was part of the second half game plan for the Brandon defense. The Bulldog front generated a lot more pressure after the intermission.
"At half, we were kind of sluggish," explained Adams. "I guess we were a little nervous, maybe just a little bit.
"We knew we had to get more pressure on the quarterback and we did that and it helped us get this win."
The win allowed Brandon to remain unblemished on the district schedule as they prepare for huge games against Meridian and Oak Grove.
"This is a big win for us," said Adams. "We just beat a good team from our district. It's a great start for us.
"We just have to keep working hard and practicing hard to get ready for Meridian."
On Saturday, Fletcher and his oldest brother Tyler Adams, a senior on the Georgetown Hoya basketball team, attended Mississippi State's win over Auburn where they had the chance to see middle brother, Nelson, help lead the Bulldog charge.
Nelson will have the chance to show his youngest brother the Bulldog ropes beginning next fall.
"I feel great about Mississippi State," said Adams. "They are on the right track.
"They had been saying that they were going to turn things around up there and they have. That's good.
"They're putting Mississippi on the map."
Adams has attended a handful of Bulldog home games this fall and has enjoyed the newly expanded Davis Wade Stadium.
"That new deck they added is cold," said Adams. "It's really good.
"My brother and them are up there just grinding for our state. That's all you can really say."
The versatile interior defensive lineman reports that he remains steadfast in his commitment to the Bulldogs.
He credits a strong bond with future position coach, David Turner.
"Me and Coach Turner have a good relationship," noted Adams. "I have been everything with Coach Turner. He's been with me through all of this and through all of the camps and all of it.
"When I told him I was committing, him and Coach (Dan) Mullen were both real excited.
"Coach Mullen even screamed."
