SAN BRUNO >> Menlo School’s Chuck Wynn proudly revealed after the Knights’ 38-28 victory over host Capuchino on Friday that he is 5-foot-10 and 170 pounds.

Wynn said it with a smile.

If any player epitomized Menlo’s state as a football program, it was the junior who gave the Capuchino offensive line fits. The team’s starting running back was forced into adding outside linebacker to his role because of injuries to teammates, and there he was, the smallest guy in the trenches drawing double teams and even being held in an effort to control him.

“They just put me in and said, ‘just eat,’ Wynn said. “Just eat away.”

In teenage vernacular, Wynn “ate” plenty. He caused havoc on defense, rushed for 90 yards on 21 carries, and picked up a huge momentum-changing first down on a fake punt that he conceived of himself.

It’s not necessarily that Wynn was the team’s biggest star. Receiver Jack Enright made two spectacular tackle-breaking plays on pass catches that resulted in scoring plays of 23 and 55 yards, and gave quarterback Jack Freehill his 11th and 12th touchdown passes of the season.

And linebacker Jamie Forese scored on a pick-six of 25 yards during a Menlo run of 28 unanswered first-half points to take a 28-7 lead.

But it was Wynn who seemed to best represent what Menlo football is all about. It’s a program with great tradition, mostly in the passing game, dating to QB phenom John Paye in the early 1980s.

But it’s also a program that, partly due to its small high school enrollment of about 600, has traditionally had small rosters — both in number of players and their physical size. On Friday, Menlo suited up 23 players.

Todd Smith, in his fifth season as head coach, is a genius in maximizing the talent at hand, even if the Knights are regularly undersized compared to their opponents. He does so by spreading his offense across the field, putting Freehill on the move, and having a good plan when things start to break down.

“Trusting each other is a big thing,” said Freehill, who completed 9 of 17 passes for 146 yards, threw for two scores and ran for two more. “My receivers know what I’m thinking. It’s nice when your receivers are amazing in the scramble drill and make me look better than I actually am.”

Somehow it all works. Menlo, which will be playing in the top-level Bay Division of the Peninsula Athletic League this year, is 4-0. And in a different sign of its success, 17 alums are playing college football, including four on Power Four programs.

Capuchino (3-1), one of the PAL’s big risers and now in the second-level De Anza Division, conceded nothing to Menlo. Quarterback Bobby Gomez had only 46 passing yards in the first half, and 169 in the second. He was 24 of 39 for 215 yards.

The Mustangs came out in the second half and appeared to stop Menlo for the second consecutive drive. But Wynn, in punt formation on fourth-and-5 at Menlo’s own 31, saw a gap and charged through it for 6 yards and a first down on what would be a 14-play touchdown drive that gave the Knights a 35-14 lead.

“That was not intended,” Wynn said. “I saw a gap and took a chance. It was crucial part of the game.”
