LOS ANGELES_At least one thing is certain as we head into the second full weekend of college football:
Pac-12 Conference teams won't go undefeated.
Someone has to lose in Saturday's showdown between No. 6 USC and No. 14 Stanford, precluding a repeat of last week's 11-0 performance that began with Utah defeating North Dakota and ended with UCLA's thriller over Texas A&M.
"It was a great start for the conference," Stanford coach David Shaw said, adding that, to him, "it wasn't a surprise."
Even if a perfect repeat won't be possible, another strong showing could nudge more Pac-12 teams into The Associated Press top 25. And the West Coast isn't the only region with something at stake in coming days.
