Viewer's Guide: National University Holiday Bowl

Some things to watch between USC and Nebraska in the National University Holiday Bowl at Qualcomm Stadium in San Diego (8 p.m. ET, ESPN, Saturday).

  1. Nebraska must stop the rush: When Nebraska loses, it’s usually because it is having trouble stopping the run. In the Cornhuskers’ three losses this year, they’ve allowed an average of 350 yards on the ground. Giving up 408 yards to Melvin Gordon didn’t exactly help that average, either. But when they allow their opponent to average more than 4 yards per carry, they are 0-3. USC’s Buck Allen was third in the Pac-12 with 111.4 yards per game.

  2. Let Kessler be Kessler: USC quarterback Cody Kessler has a plus-32 touchdown-to-interception ratio this season (36-4). That's the third highest in FBS this season. And when he looks to Nelson Agholor, Kessler finds him better than three of every four tries (76.4 percent). That's the best completion percentage for a QB/WR duo among Power 5 schools. When he looks to Agholor beyond 15 yards, Kessler is 18-of-25 with five touchdowns and no interceptions.

  3. Ameer versus the world: When Nebraska running back Ameer Abdullah faces seven or fewer defenders in the box, he’s averaging 7.2 yards per rush. However, when teams stack the box with eight or more defenders, that number drops drastically to 3.4 yards per carry. This presents the game-within-the-game chess match, because Abdullah has 791 yards rushing between the tackles and 731 yards when he hits the edge. USC had one of the top rush defenses in the Pac-12, allowing 3.9 yards per carry and 132.5 yards per game. The Trojans did, however, yield 18 touchdowns on the ground, which ranked in the bottom half of the conference.

  4. Who is motivated? Always a popular topic in bowl season. Despite the surprise hire of Mike Riley, Bo Pelini continued to leave chaos in his wake. Plus, interim coach Barney Cotton might already have one foot out the door on his way to joining Tony Sanchez at UNLV. USC, by all accounts, had an up-and-down season with a couple of "what if?" moments. Are they happy to be in a bowl under first-year coach Steve Sarkisian, or are key players already eyeballing the NFL combine?
