PASADENAAfter UCLA quarterback Brett Hundley strutted into the end zone, waves of cardinal-clad fans poured out of the Rose Bowl.

The gesture was one of recognition, acknowledgement of a Los Angeles football revolution. Hundley’s score, the exclamation point on his four-touchdown performance, slammed the door shut on UCLA’s 38-20 win over crosstown rival USC.

As players leapt in the stands to celebrate with fans, distant were memories of the Trojans’ 50-0 destruction of the Bruins in 2011, a game that Hundley, then a true-freshmen, watched from the sidelines.

Billed as the savior of a UCLA team that could never escape their rival’s shadow, Saturday’s victory cemented Hundley’s perfect 3-0 record against the Trojans; one of the quarterback’s stated goals since taking over the starting job in 2012.

Following a shocking first-quarter pick-six by linebacker Anthony Sarao, Hundley recovered brilliantly, punching holes in the Trojans’ defense to the tune of 326 yards and three touchdowns.

The victory was also a statement by third-year UCLA coach Jim Mora, who has beaten three different USC coaches in as many years by a combined score of 111-62.

Mora’s defense, considered one of the nation’s best, stifled USC and quarterback Cody Kessler, limiting the Trojans to 200 yards and a touchdown through the first three quarters.

Defensive linemen Owa Odighizuwa and Ellis McCarthy spent the evening in the USC backfield, and linebacker Erik Kendricks was a constant menace for the Trojans, totaling 14 tackles and a phenomenal diving interception of Kessler.

On the other side of the ball, the UCLA offensive line, much maligned after giving-up 31 sacks on the season, protected Hundley and paved the way for 135 rushing yards.

The ninth-ranked Bruins, now atop the PAC-12 South, face a Friday match-up with Stanford (6-5), a team whose physical brand of football has given UCLA fits since Mora took over the program. The Cardinal present themselves as a fitting final test for the Bruins, who boast a 3-0 record against UCLA during the Mora-Hundley era.

If victorious, the Bruins would secure the PAC-12 South title, setting up a battle for PAC-12 supremacy with second-ranked Oregon.
