It happens all the time: We enter a college football Saturday, look at the schedule and say "meh, this could be a down week" -- only to see it explode.
Saturday was no different, as we went into the day with nine undefeated teams, and incredibly, four fell. What's even more staggering is two of the remaining unbeatens were on a bye, meaning that more than half the teams who went into the day undefeated didn't emerge that way.
We're now down to five undefeated teams: Alabama, Michigan, Clemson, Washington and Western Michigan.
As for everyone else? Here's who lost and how it happened.
No. 10 West Virginia (lost 37-20 at Oklahoma State)
Of all the undefeated teams to fall Saturday, West Virginia did it in the least dramatic fashion. The Mountaineers were simply outplayed by a good Oklahoma State team in Stillwater to fall to 6-1.
Mason Rudolph led the way for the Pokes with three touchdown passes, while Skyler Howard had one of his worst games of the season for the Mountaineers. He threw two interceptions, and the Mountaineers turned the ball over three times in the loss.

No. 8 Baylor (lost 35-34 to Texas)
Charlie Strong needs all the positive momentum he can get, and he got it in dramatic fashion in this wild win in Austin. The Longhorns trailed by eight midway through the fourth quarter, before a touchdown got them within two, and a Trent Domingue 39-yard field goal with under a minute to go gave them a lead they wouldn't relinquish.
Baylor can get back on track next week, when it faces a struggling TCU squad that lost to Texas Tech on Saturday.
No. 7 Nebraska (lost 23-17 in overtime vs. Wisconsin)
Nebraska asserted itself well against one of college football's best defenses, but the Huskers couldn't have counted on Badgers running back Dare Ogunbowale. The senior rushed for 120 yards and had the go-ahead score in overtime to give Wisconsin the wild win at Camp Randall.
Nebraska still controls its own destiny in the Big Ten West standings, but winning out won't be easy. The Huskers travel to Columbus to face Ohio State next Saturday.
No. 13 Boise State (lost 30-28 to Wyoming)
Of all the wild finishes Saturday, this one might have been the craziest -- with Boise State losing on a safety late in the game. That's right, a safety!
The loss was especially crippling for the Broncos, as they now fall to second place in the "West" standings in the Mountain West and were almost certainly eliminated from New Year's Six bowl game consideration.
