Actually, USC never really left. The Trojans are just concealed under the clouds of NCAA sanctions and postseason ineligibility. But they do appear on the way to returning to college football's A-list.
The BCS standings won't show it. The Pac-12 championship game won't either. Still, it's quite clear USC has re-emerged as the best team in the Pac-12.
The victory at Oregon - the probable Pac-12 champion - would seem to prove that point.
So would that the Trojans have won six of their past seven - usually in dominating fashion. Their only loss in that stretch was a controversial triple-overtime setback to Stanford, the conference's highest-ranked team.
Indeed, in this upset-infested season, USC has resurfaced as one of the best team in the nation.
And if quarterback Matt Barkley and offensive tackle Matt Kalil, among others, decide to stay in school and bypass the NFL draft, USC could be a national championship contender in 2012.
But that's putting the cart before the Trojan horse.
"We just worry about what we can control and try to keep moving away from the clouds and give our fans and players something to be excited about," second-year Trojans coach Lane Kiffin said. "Fortunately, we've been able to do some of that and we have an opportunity on Saturday to do some more of that."
The latest opportunity comes in the Coliseum, when the Trojans close their season with a chance to notch their 10th victory, continue to climb in The Associated Press poll and perhaps knock crosstown rival UCLA out of the Pac-12 championship picture.
With USC ineligible for postseason play because of NCAA sanctions stemming from the Reggie Bush scandal, the Pac-12 South Division has become a mess.
Should USC defeat the Bruins for the fifth consecutive, the eligible division leaders - UCLA, Arizona State and Utah - could finish in a three-way tie with 5-4 league records.
In that case, Arizona State would represent the South (most likely against Oregon) in the first Pac-12 championship game. UCLA gets in the championship game by beating USC or with an Arizona State victory over Cal combined with a Utah loss to Colorado. Utah reaches the championship game if the Utes beat Colorado combined with losses by UCLA and Arizona State.
If USC beats UCLA, the Trojans would close their season with a two-game lead over every other team in the division, and it would give their fans reason to be excited.
The Trojans have 10 offensive starters and nine defensive starters who could return next season. That includes wide receivers Robert Woods and Marqise Lee and running back Curtis McNeal, who was a backup for much of the season but has a good chance to reach 1,000 rushing yards.
That list includes Barkley and Kalil, juniors who project to be first-round picks if they opt to go pro.
"We either both leave or both stay," Kalil told Los Angeles-area reporters recently. "I think that's the way it will play out."
If they stay, USC will have a proven, experienced starting lineup, a potential Heisman favorite in Barkley and the nation's top offensive lineman protecting him.
"I know where I'm at draft-wise, but I also know the other side of it - Matt and I coming back and doing something really special for this university," Kalil said. "That's really crossed my mind as something I would want to do."
The USC faithful certainly hope they do return.
But until that's determined, USC fans can at least be satisfied with knowing the Trojans are back among the country's top teams.
Best matchup: Stanford run offense vs. Notre Dame run defense. The Cardinal has a solid offensive line and a group of productive tailbacks led by Stepfan Taylor, who has rushed for at least 95 yards in five of the past six games. The Cardinal average 209 rushing yards per game. Meanwhile, Notre Dame's defense, led by LB Manti Te'o, is solid against the run. The Irish have held eight opponents to 145 or fewer rushing yards. The Irish have allowed just eight rushing TDs.
Players on the spot: Arizona State's defense. The Sun Devils have allowed more than 400 yards in each of the past five and no fewer than 29 points in each of the past three games. As a result, Arizona State, which once seemed in control of the Pac-12 South Division race, needs a victory over Cal to stay alive. The Sun Devils have given up 896 passing yards in the past two games. That's an ominous figure considering Cal's receiving duo of Keenan Allen and Marvin Jones is among the best in the conference.
Keep an eye on: Utah RB John White. The Utes are 7-0 when White rushes for 100 yards. He has hit triple digits in five of the past six games and has scored two touchdowns in each of the past three. His 14 rushing touchdowns equals the single-season school record. White faces a Colorado defense that is ranked 97th in the nation against the run and has allowed four 100-yard rushers this season.
Numbers game: Oregon junior RB LaMichael James already has set school records with 4,562 career rushing yards, 1,731 single-season rushing yards and 288 single-game rushing yards. He's also the leader in all-purpose yards with 5,310. Next, he needs one more touchdown to set the Ducks' scoring record. James currently has 318 career points to trail Jared Siegel by five points.

"All I've hard all year is the computers don't like Stanford. The computers haven't programmed themselves. To have a one-loss Pac-12 team behind a one-loss ACC team [Virginia Tech] means that the computer values the ACC more than it values the Pac-12. I don't believe that is accurate." - Stanford coach David Shaw, on the flaws of the BCS system
Poll watch: No. 6 Stanford and No. 10 Oregon are the only Pac-12 teams in the BCS standings. They could move up with victories, but don't figure to climb much. USC has surged to No. 10 in The Associated Press poll, but is ineligible for the coaches' poll, the Harris Poll and the BCS standings, though the Trojans' results are taken into account by the BCS computers.
