Asked what challenges El Segundo High football presents, Golden Valley coach Dan Kelley didn’t hesitate. “They’re 10-1,” he said. Meaning: The Eagles present myriad challenges and have for almost every team they’ve faced. No. 2-seeded El Segundo enters Friday’s CIF-Southern Section Division 7 quarterfinal at Canyon High averaging 34 points per game on offense and allowing just 10 points on average defensively. and a playoff game (14-10 over Ayala of Chino Hills last week). To continue the Cinderella story, though, Golden Valley must stop the run. “No. 4 (for El Segundo) is a slasher. He’s going to be one of the best backs we’ve seen this year,” Kelley said. No. 4 is 5-foot-10, 190-pound Taz Tauaese, a senior who’s rushed for 1,049 yards and 16 touchdowns. He’s averaging 8 yards per carry. The Grizzlies rushing attack has averaged 181 yards rushing per game, headlined by KJ Maduike. The senior has racked up 1,213 yards and 11 touchdowns. And if El Segundo stacks the box, quarterback Josh Valano and receiver Jalin Lewis can make big plays in the passing game. However, West Ranch and Ayala have held Lewis to six catches for 54 yards over the last two games.
