While Southern California is ruling the college football world as the No. 1 ranked team in the CBSSports.com 120 and Oregon is hanging tough at 3-0, the rest of the Pac-10 isn't so fortunate.
Seven of the conference's 10 teams lost this weekend with three teams falling more than 20 spots and if this trend continues, the Pac-10 is going to have a hard time filling all its bowl slots. After the BCS, the Pac-10 has six bowl slots to fill, meaning teams from the MAC, MWC and WAC could slide in to fill if the Pac-10 doesn't get enough bowl-eligible teams.
Falling the farthest was UCLA and California, each dropping 24 spots.
The Bruins went from No. 25 to No. 49 after getting smoked by BYU 59-0, while California dropped from No. 27 to No. 51 after losing to Maryland. The Terrapins were ranked No. 99 before the game after losing to Middle Tennessee State the week before.
"When you take a tail-whipping like we took, the first thing you want to do is throw away the tape," UCLA coach Rick Neuheisel said. "The second thing is to analyze it ad nauseam because you have to fix it."
UCLA will have a chance to fix it against another conference faller as it plays Arizona this week. The Wildcats dropped 21 spots from No. 54 to No. 74 after losing to New Mexico, which came into the game at 0-2.
One of the biggest shockers of the weekend was No. 14 Arizona State losing to UNLV in overtime. The Las Vegas Review-Journal is calling it one of the biggest wins in UNLV history and UNLV coach Mike Sanford declared it "the biggest win of my life."
The Sun Devils fell 12 spots from No. 14 to No. 26 and now have to take on Georgia this weekend.
Could they have been caught looking ahead?
"It was a nightmare," coach Dennis Erickson said. "It’s sickening. It starts with me. I didn’t have them ready to play. I’ll take the blame."
The bottom-feeders of the conference -- Washington and Washington State could both be in for a long season. Washington dropped 15 spots from No. 79 to No. 94, while Washington State dropped from No. 101 to No. 105. Stanford fell from No. 56 to No. 64 after losing to TCU 31-14.
It wasn't all bad news for the Pac-10, Oregon State moved up two spots after beating Hawaii.
