Peacock, the team's starting quarterback, rushed for 450 yards, threw for 1,200 yards and contributed 13 touchdowns as the Class 2A Cowboys made it to the state championship game at Florida Field against Hollywood Chaminade.
While Madison County was plagued by mistakes that day, losing to Chaminade 27-0, Peacock is determined to help the Cowboys make it back to Gainesville next season.
"We simply picked the wrong afternoon to have a bad game," Peacock told TheTerritory. "But that game will serve as motivation over the summer. We want to get back to the Swamp."
The 5-foot-11 Peacock will have to do it by putting in double duty at quarterback and safety. Coach Frankie Carroll says Peacock is simply too good not to play on both sides of the football next season.
Peacock started at safety as a sophomore before switching to quarterback last season.
"We may have to play him both ways," Carroll said. "He's an exceptional athlete, and is probably the strongest kid we have."
It shows, too.
Peacock, 17, maxed out in his weight-training sessions Tuesday morning. He benched 320 pounds, had 535 pounds on the trap bar and 300 pounds on the power clean. Carroll said Peacock can basically "squat whatever he wants to put on the bar."
And if you are looking for fast, there's no need to look very far.
Peacock has been clocked at 4.41 in the 40, according to Carroll.
Peacock says he's looking forward to the double-duty next season.
"Both positions are fun to play," Peacock said. "At quarterback, you have to be able to run and throw and be a leader. On defense, I feel like I can cover anyone. I have the speed to cover and I consider myself a hard-hitter. I like breaking down and wrapping people up."
Peacock, who is a solid student -- he had a 3.4 grade-point average his first semester -- and will take the ACT for the first time in April, has already attracted letters from North Carolina, Syracuse, Alabama, Iowa and Ol' Miss.
Peacock said he grew up a fan of the Florida State Seminoles and would welcome the chance to play in nearby Tallahassee.
At the moment, Peacock is also concentrating on baseball, where he is an outfielder for the Cowboys. Madison County plays Lake City and Hamilton County in preseason games Thursday and Friday.
Still, football isn't far from Peacock's mind.
"We should be pretty good next season," Peacock said. "Defensively, we are going to be very quick. We have a lot of speed. We also have skill on offense. We just need to get our offensive line settled."
