The largest lead in a back-and-forth affair was 21-7 by the South until the North rallied with two touchdowns to tie before forging the 28-24 lead.
That's when Hasuga made a key interception with 7:30 to play in the fourth quarter, picking off the North squad.
The South then used just two plays to go 21 yards and scored when Thiverege hit Rickert with a 19-yard touchdown pass.
"The interception (was key). That was the biggest play of the game, I thought," South coach Jim Keiser of Danville said. "We got the lead back, they threw it over the middle and Andrew Hasuga made a great play on it and picked it off and we got the lead … that was a big part of the game."
A bench-clearing brawl after a kickoff return midway through the fourth quarter resulted in Thiverege and Danville's Cale Rice being ejected for the South.
The North started the game with a 25-yard strike from South Williamsport's Tyler House to McDougan with 5:12 left in the first quarter. The South immediately responded with an 81-yard kickoff return by Southern Columbia's Joey Kleman, the first of three straight scores for a 21-7 lead.
"We struggled a little bit in the beginning. They returned a kick there to make it 28-24, I believe, and really started putting it to us, but we fought back and it was amazing," Rickert said.
The South's best weapon was its quarterback trio of Thiverege, Rickert and Southern Columbia's Taylor Young, who combined for 266 yards through the air.
Young put the final nail in the coffin against the North when he took off up the middle on a second-and-9 from the South's 36 for a long touchdown to lead 45-28 with just 3:37 to play.
The North's offense sputtered early, starting the game with seven drives of its first eight ending with a punt followed by a drive ending with an interception.
