It didn't take long for the celebration to begin on the McClymonds High sideline Friday when the Warriors pulled off the biggest upset of the young season by beating then-No. 8 Pittsburg 26-21.

Not long after the teams exchanged handshakes, Mack coach Curtis McCauley was on the bottom of a dog pile, with his players thoroughly enjoying the chance to pile on their coach.

The win was big for several reasons.

It showcased the talents of one of the area's top recruits, Marcus Peters, who caught six passes for 173 yards and two touchdowns, including the game-winner.

It gave the Warriors a second straight quality win after they beat Ferndale -- which has the sixth-best winning percentage in California since 2000 -- by an 18-0 score the previous week.

It also helped boost Mack into this week's Bay Area News Group East Bay poll at No. 10.

But the win was bigger than that. It's probably the most significant nonleague victory by an Oakland Athletic League team in at least five years.

Not since 2004, when Skyline beat Monte Vista, had an OAL team defeated an NCS Division I (or formerly 4A) opponent that had advanced to at least the section semifinals the previous season.

McClymonds' win in 2005 over Crenshaw-Los Angeles -- the Los Angeles City Section champion that season -- is probably the most recent victory to carry a similar weight.

"It just shows anybody can beat anybody," Peters said. "We just play hard every week."

The feat is even more impressive given Mack's enrollment, which is 247 according to the Oakland Unified School District.

"It's really great," McCauley said. "We've only got 22 players. Our guys play both ways. The seniors really came together."

Mack will truly be road warriors Friday when it travels roughly 300 miles to face McKinleyville at 7 p.m. with rain in the forecast.

Bucking bronco: With 118 points in its first two games, Northgate certainly seems like a logical contender for the Diablo Valley Athletic League title.

But Broncos coach Justin Lowell has seen this type of start before. In fact, his squad looked almost this strong last season when it also won its first two games by large margins.

The difference this season has come on the defensive side of the ball. Whereas the 2009 Broncos allowed 53 points in their first two wins, this year they've given up only 25.

Where things fell apart last year was in the league season. Injuries derailed Northgate's hopes at contending, and the Broncos' double-wing, double-tight end offense averaged just 11 points per game in five DVAL contests.

This year, they returned two outstanding talents to build on in Cameron Stover and Matt Butler. Stover has rushed for 427 yards and scored six touchdowns (one on defense). Butler has 208 receiving yards and seven total touchdowns (five receiving, two rushing).

Before the Broncos can focus on the league DVAL chase, they'll have to navigate the most difficult part of their nonleague schedule. This week, they travel to play an improving Dougherty Valley squad and next week they'll head across Walnut Creek to take on rival Las Lomas. League play starts Oct. 15 with a game against College Park at Diablo Valley College.
