The Tigers (2-0) took over at the J.L. Mann 34-yard-line, scored the first touchdown of the game five plays later and went on to a 27-6 triumph.
Blue Ridge scored 27 unanswered points over the next three quarters and shut the Patriots (1-1) out of the end zone until the final play of the game.
"It gave us a bunch of momentum," senior wide receiver Brennen Griffin said of Dogan's early interception. "We just fed off that and it really helped us get the win."
So did Griffin, who was the favorite target of sophomore quarterback Ty Montogomery.
Montgomery completed 17 of 23 pass attempts for 228 yards and two interceptions and opened the scoring with a 1-yard sneak for a touchdown. Griffin caught nine of those pass attempts for 139 yards, doing most of his damage during a second-quarter scoring drive that put the Tigers ahead 20-0.
On that drive, Griffin had three catches for 74 yards, setting up a 2-yard plunge by Jonathan Bull.
While Montgomery and Griffin put up big numbers through the air, all four of Blue Ridge's touchdowns came on the ground.
Mikal Robinson's 70-yard burst up the middle put the Tigers ahead 14-0 with 6:08 left in the first quarter. He added an 11-yard touchdown run in the fourth quarter and rushed for 104 yards on 15 carries.
"Our guys play hard on both sides of the ball," said Blue Ridge head coach Wade Cooper. "I just told them they're probably the hardest playing group I've ever coached."
Defensively, the Tigers held Mann to 160 yards in total offense and four turnovers -- two fumbles, an interception and once on downs.
The shutout stood until Mann quarterback Ryne Strickland, who completed 7 of 22 passes for 77 yards, found receiver Jake Riggs in the end zone from 17 yards out on the final play of the game.
