"For the DBs, this is probably the best receiving corps we've been up against," he said.

The Trojans' leading receiver, Nelson Agholor, has 97 receptions for 1,223 yards, an average of 12.6 yards per catch. He's also caught 11 touchdown passes. For comparison, Nebraska's Kenny Bell has 40 catches for 717 yards and five TDs.

USC quarterback Cody Kessler has thrown for 3,505 yards this year (292.1 per game).

"I would probably say he's the best quarterback (we've seen) by far," Davie said of the junior. "That goes without saying; he's got a great arm and he gives all his receivers a chance to make plays. ... We're really excited for this game, because we know we're going to get tested in the defensive backfield, so we've gotta be on top of our game."

* TEMPO A CHALLENGE: Collins said one of the biggest reasons USC's offense is so hard to stop is because the Trojans often run an up-tempo system. Collins said the challenge isn't so much physical as it is mentally taxing. Defenders have to get the play from the sideline in a hurry, which can cause confusion at times.
