Clayton Valley (4-1) at College Park (3-1-1), Friday, 3:30 p.m.

  • Clayton Valley, the defending Diablo Valley Athletic League champion, faces its toughest competition since losing to De La Salle in its season opener. Since that 34-14 loss to the Spartans, the Eagles have outscored their opponents 219-20. Miles Harrison is Clayton Valley's leading rusher, but his workload has been limited because of the blowouts. College Park will be looking to get out to a strong start in its DVAL opener after finishing fourth last year. The Falcons come into the game having won two straight behind quarterback Dimitri Salido, who threw for 189 yards, rushed for 93 and accounted for three touchdowns in a 32-20 win over Hayward two weeks ago. Clayton Valley beat Hayward 49-7 last week.

    Freedom (2-3) at Deer Valley (5-0), Friday, 7 p.m.

  • Freedom begins defense of its Bay Valley Athletic League title against one of its biggest threats. Deer Valley was a perfect 5-0 in nonleague games and is coming off an impressive 45-34 victory over Sac-Joaquin Section power Vacaville last week. Dual-threat quarterback Nsimba Webster and his twin brother Nzuzi are in the middle of strong seasons for Deer Valley. Freedom had a bye last week and prized running back recruit Joe Mixon used the break to take an official visit to Oklahoma. Mixon played his most productive game of the season two weeks ago, rushing for 305 yards and scoring six touchdowns in a 49-21 win over Castro Valley. Deer Valley linebacker Malik Hutchings is coming off a huge game against Vacaville in which he totaled 19 tackles, four forced fumbles and two fumble recoveries.

    Foothill (6-0) at California (4-1), Friday, 7 p.m.

  • Three weeks into the East Bay Athletic League season, both the Falcons and Grizzlies look the part of league title contender. Foothill's stingy defense, which has given up an average of just 6.8 points, will be tested by bruising running back Blake Bierwith, quarterback Cameron Owens and the rest of the Cal High offense. The Falcons have yet to play a close game in their undefeated start. California's only blemish was a two-point loss to Pittsburg in Week 2. Since then, the Grizzlies have defeated Castro Valley, Granada and Amador Valley with the defense stepping up since the start of EBAL play. This week, the Grizzlies will be tasked with slowing the Falcons' highly-regarded junior duo of QB Kyle Kearns and WR/DB Isaiah Langley. History is on Cal's side -- coach Eric Billeci and the Grizzlies haven't lost to Foothill since 2008.

    Amador Valley (4-1) at San Ramon Valley (2-3), Friday, 7 p.m.

  • Amador Valley is coming off its first loss of the season, 29-7 to California, after a hot start. The Dons managed just seven points in the loss, the first time they've been held to under 28 points all year. San Ramon Valley was glad to get EBAL play started against Livermore, winning 41-10 to snap a three-game losing streak. Running back Marcus de la Pena rushed for 204 yards, the third time he's eclipsed the 200-yard rushing mark in five games. Amador Valley and SRV played two thrillers last year. The Wolves won the EBAL matchup 22-15 on their way to a co-league title but the Dons got even in the postseason, winning 28-25 in the NCS Division I quarterfinals.

    Encinal (4-1) at Bishop O'Dowd (1-4), Friday, 7 p.m.

  • The West Alameda County Conference-Foothill Division looks wide open. Could the Jets or the Dragons eventually claim the title over defending champion Berkeley? Encinal has only lost to WCAL power Serra, though the Jets' offense doesn't produce many points. Only once all season have they scored more than two touchdowns. O'Dowd has prepared for WACC play with a challenging schedule; maybe too challenging. The Dragons have only beaten Arroyo while losing big to Terra Nova-Pacifica, Valley Christian-San Jose and James Logan.
