Two football teams used to scoring — and scoring often — will do battle Saturday afternoon at Clarion University’s Memorial Stadium.

District 9 champion Karns City (12-1) takes on WPIAL champ South Fayette (13-0) in a 1 p.m. kickoff to determine who reaches the PIAA Class AA semifinals.

The Gremlins have not scored less than 35 points in a game during their current 11-game winning streak. The Lions have not been held below 31 points in a game all season.

“They are going to score points on us,” KC coach Ed Conto said. “They do some unique things offensively that most high school teams just can’t do. It takes a special quarterback to run their offense and they have one.

“We have to answer their scores. All we have to do is score one more point than they do.”

South Fayette coach Joe Rossi said the road to the state title is bigger than the WPIAL crown.

“We tell our kids, when they go off to college and tell people they are a WPIAL champion, no one will know what that means,” South Fayette coach Joe Rossi said. “Tell them you’re a state champion and everybody knows what it is.

“The WPIAL tournament is over. This is the first step toward that bigger goal.”

The Lions finished 15-1 in 2010 and lost in the state title game. The Gremlins have never been to the state semifinals.

“This is the fourth time we’ve gotten to the (quarters) and we’ve never gotten past this point,” Conto said. “One of these times, we’re going to crash through.

“I don’t see why it can’t be this year.”

Rossi’s teams have won 56 of 63 games over the past five years and South Fayette is coming off a thrilling 34-28 win over Aliquippa in the WPIAL championship game at Heinz Field.

“Believe me, nobody is looking past Karns City,” Rossi said. “Their running backs run hard and that quarterback is impressive.

“We faced Brockway in this round back in 2010 and struggled in the first half. Karns City hits hard and they’re a veteran group. We’re expecting a very good game.”

Expect South Fayette to put the ball in the air quite a bit.

Junior quarterback Brett Brumbaugh has completed 172 of 267 passes for 2,781 yards, 31 touchdowns and five interceptions. His top two receivers are Conner Beck (60 catches-752 yards-9 TDs) and Justin Watson (51-1,205-15).

Watson is 6-foot-3, 195 pounds while Beck is 6-0, 175.

“Those kids are basketball players with good speed who can go up and get the ball,” Rossi said.

The Lions have a 1,000-yard rusher in senior Grant Fetchet who has produced 1,103 yards and 19 touchdowns on 136 carries.

“If defenses back up on us, we can run the football effectively,” Rossi said.

Brumbaugh is the younger brother of Christian Brumbaugh, who guided South Fayette on that 2010 postseason run and is now a quarterback at William & Mary.

“Brett stands about 6-4 and is just like his brother, a straight drop-back passer who puts excellent touch on the ball,” Rossi said.

Despite the Lions throwing the ball 25 times a game, they’ve allowed only four quarterback sacks all year.

“They run a great scheme,” Conto said. “They spread you out and they’ll flare that running back out on patterns. Somebody has to go with him. They often have five linemen blocking four. It’s hard to get to that kid.”

Defensively, South Fayette is led by inside line backer J.J. Walker and safety Beck.

Junior place-kicker Brian Coyne booted two key field goals against Aliquippa and connected on a trio of 3-pointers during the regular season.

KC’s offense, of course, packs a punch as well. Tyler Kepple has thrown for 1,672 yards and 30 touchdowns, though all five Gremlin touchdowns were on the ground in last week’s 35-14 triumph over Chestnut Ridge.

The Gremlins have rushed for 3,784 yards and 55 TDs this season despite having no one anywhere near 1,000 yards on the ground.

Tristan Rhoades has 680 yards rushing and seven touchdowns, Zach Moore 658 and 10 TDs, Wyatt Everetts 621 yards and nine TDs.

Dakota Mohney has 37 catches for 569 yards and seven TDs, Logan Moroney 34 catches for 571 and nine scores.

The Gremlins turned the ball over four times last week against Chestnut Ridge.

“Without the turnovers, we may score 50 points and maybe they score none,” Conto said. “We cannot afford turnovers Saturday. We have to take advantage of every opportunity we have.

“I’ve got some kids on this team who are talented, but are capable of giving more than they’ve shown. We’re going to need that Saturday.”
