Led by the tailback tandem of sophomore James Williams and senior Teddy Arlington, Burbank has seen the two combine for more than 2,000 yards rushing.
Valencia said Norwalk (8-2), which finished third i the Suburban League, runs a double-wing T offense behind a huge offensive line.
"They're definitely a running team," Valencia said. "We know how they're gonna come after us. It's just a matter of if we're gonna be ready."
Averaging more than 370 yards rushing per game, the Lancers boast three running backs with more than 600 yards rushing and at least eight touchdowns, led by Rashaad Penny, who's rushed for more than 1,500 yards and 24 touchdowns.
Having won two straight and six of their last seven, the Bulldogs are on the heels of a 37-14 win over rival Burroughs and Valencia likes where his team is headed.
"I think it's good momentum that's gonna carry over," said Valencia, whose Bulldogs, should they win, would face either Downey or Rowland in the quarterfinals.
Bell-Jeff, on the other hand, is coming off a 34-14 Santa Fe League loss to St. Monica. But a 4-6 record and a 2-2 showing in league has led the Guards to the playoffs and first-year coach David Machuca is plenty pleased with that.
"First of all, our goal was to get in the playoffs. Just to get in is a huge accomplishment for the program," he said. "We're gonna have our hands full, but we're gonna give it our best shot."
Rio Hondo is the defending division champion and has won seven games in a row, including a 4-0 run to a Prep League title.
"They're disciplined and they play hard," said Machuca of a program that boasts 13 division championships.
The Kares are led by running back Nate Tayco, who averages nearly eight yards a carry, and have scored more than 40 points in four straight games, including a 49-0 win over Pasadena Poly on Friday. It's the same Poly team that Bell-Jeff beat, 50-49. The Guards are led by standout running back Josh Martinez, who's rushed for more than 1,700 yards and 26 touchdowns.
Should the Guards pull of the upset, they would play either Saddleback Valley Christian or Desert.
Both games are set for 7:30 p.m. starts.
