UCLA quarterback Brett Hundley's running ability isn't the only thing on USC's mind.
When the Trojans play the Bruins on Saturday at the Rose Bowl, they must also control running back Paul Perkins.
Perkins has averaged 117.2 yards a game and has scored six touchdowns. He is second in the Pac-12 in rushing behind USC's Javorius Allen, who averages 118.4 yards per game.
"You can see his comfort level running it," Coach Steve Sarkisian said.
Perkins also has 24 receptions, two for touchdowns.
"They utilize him a lot in the screen game," Sarkisian said. "He's been effective catching the ball out of the backfield. It just presents more problems."
