Brown, a 6-foot-2, 190-pounder, began his prep career at North Stanly High, where he split time at quarterback and receiver in a wing-T offense. In any given game, he would catch, throw and run the football.
"We knew what he was capable of because [North Stanly] is a county rival and we played against him before," Little said.
In mid-September, Brown's family moved into South Stanly's district and Brown joined the football team, which had been quarterbacked by Detrick Allen since the 2007 season.
"At first, I wasn't sure how much playing time I was going to get and I wasn't sure where I was going to play at," Brown said. "They had Detrick at quarterback and I knew he started at quarterback last year.
"I just came in and tried to work hard so that I could get some playing time somewhere."
Brown spent the next month on the bench learning South Stanly's offense.
"It was kind of hard, because the spread [South Stanly runs] is mostly a passing offense, where the wing-T is a lot of misdirection running," Brown said.
Eight games into the season, Brown replaced Allen at quarterback. Allen was shifted to wide receiver and received an increased role on defense.
"Once he learned the system, I moved Detrick to free Detrick to do a lot more things," Little said. "And I wanted somebody on the opposite side of Terry [Shankle]. It just worked out great and both of them were fine with the move.
"Detrick could do a little more, as far as with the ball in his hands then Desi could. But Desi is a little better passer. Desi is more of a true quarterback than Detrick. Detrick is just an athlete back there."
With an understanding of the offense, Brown fit perfectly in a spread system that is only as good as the quarterback running it.
"We run a pretty basic system, but we have a lot of checks," Little said. "Having a smart quarterback that can [make those checks], makes the offense run that much better. He's a smart kid and one of those guys that can [make the checks]. He's reading on about everything – we have eight run plays and six of them are reads."
Brown is a 4.0 student and scored a 1040 on his first taking of the SATs.
In just six games, Brown accumulated 917 yards on 53-of-81 passing and 379 yards rushing. He scored five touchdowns on the ground.
Little believes Brown could continue to play quarterback at the next level.
"I've never had a Division I quarterback, but when he goes to camps and combines, he throws as well as anyone there," Little said. "He's a runner/athlete, but he can throw."
Brown says he is mostly being recruited as an athlete. The schools expressing the most interest in him include Duke, Georgia Tech, North Carolina, Wake Forest, and West Virginia.
"Wofford called [Wednesday] and said they would offer him, but they don't think he'll stay on the board," Little said. "They think Desi will get some Division I-A offers."
Brown is still waiting on his first Division I-A offer, but a couple of schools appear close.
"West Virginia called [Wednesday] and said they were doing their breakdown of film today, and they were going to meet tonight and in the morning and then decide if they were going to offer," Little said. "And then Coach [Todd] Spencer from Georgia Tech, he thinks they're going to offer both [Brown and Allen].
"Georgia Tech runs the perfect system for him."
Brown, who prefers to play quarterback but is open to a position move, says schools that run an option-heavy offense are most attractive.
Most schools, though, want to see Brown workout in person, before deciding whether to offer.
"Everybody says ‘Coach we like him,' but everybody wants to see a quarterback [perform in person] unless you're one of the top quarterbacks in the country," Little said. "Wake [Forest] and Duke want him to come to their camps."
Brown, who has attended Wake Forest's Junior Day, says he will accept both Duke's and Wake Forest's invitation, and also is considering camping at UNC.
