Was Oregon's 13-0 second quarter lead a sign that there is a chink in the Trojans' armor? Perhaps. Or was USC's 45 unanswered points a sign that they have an unstoppable offense that can score at will? At this point, can anyone hope to defeat the two-time defending national champions who have won 25 straight?

USC still faces four ranked teams that should give the Trojans some trouble. And three of these games will put the Trojans in hostile road situations. And you can bet that these teams have seen USC's vulnerable side. Consider this: In the first twenty minutes of yesterday's game at Oregon, USC committed 9 penalties for 78 yards. Quarterback Matt Leinart was rattled early and by halftime had completed only 12 of 25 passes with as many touchdowns, one, as interceptions. The second half was a different story as USC completely dominated overmatched Oregon and won convincingly, 45-13. Do any of USC's remaining regular season opponents have a chance?

at #14 Arizona State (10/1): Tuning up for the game next week at Sun Devil Stadium, ASU beat up the Beavers in Corvallis, 42-24. Sun Devil quarterback Sam Keller leads the nation in touchdown passes with 16 and almost led his team to a victory over #4 LSU two weekends ago in Tempe, falling short in the last moments of the fourth quarter.

at #13 Notre Dame (10/15): The Irish face Purdue in West Lafayette next week and then get a bye week to prepare for the game against the Trojans. USC has owned Notre Dame lately, winning each of the last three games by a 31-point margin. But under new head coach Charlie Weis, the Irish offense will not be intimidated by USC as they have been in recent years. This game should be a back and forth shootout.

at #12 California (11/12): Despite losing JJ Arrington and Aaron Rogers, the Bears are off to a 4-0 start, albeit against limited competition. Still, this game has proved tough for Trojans in recent seasons. The Bears were the last team to defeat the Trojans before the 25-game winning streak began. And last season in the Coliseum, Cal was a dropped pass in the end zone away from upsetting the Trojans in L.A.

#20 UCLA (12/3): The Trojans close the regular season at home against crosstown rival UCLA. Last season, the Trojans narrowly escaped the Rose Bowl with a win over the Bruins in a down year for UCLA. But UCLA is playing much better football this year, as evidenced by their 3-0 start. And in a rivalry game of this magnitude, you can throw the records out the window and expect this to be a hard-fought and close game that will come right down to the wire.

But in reality, it may be that the only ones that can beat the Trojans are the Trojans themselves. If the Trojans bring their A-game week after week, there's not a team on their schedule that matches up with them. Now having to face Texas or Virginia Tech in a bowl game may bring the Trojans an opponent that can match up with them. But it's way to early to even think about that now, isn't it?
