Get ready for seismic shifts in the Sweet 16 from now on. There are thirteen undefeated teams remaining and thanks to head-to-head competition coming up between several of them (LSU-Auburn, Nebraska-Missouri, TCU-Utah, to name a few) only seven can possibly end up perfect at the end of the regular season.

Oregon’s explosive offense continues to impress. I expect Nebraska to handle Texas this week and verify their #4 ranking. Oklahoma has the most impressive current four-game winning streak (over Florida State, Air Force, Cincinnati, and Texas) of any ranked team.

#1 The Buckeyes assume the top spot with their 38-10 win over Indiana and Alabama’s loss. Don’t miss a monster clash this Saturday in Madison when Ohio State battles #15 Wisconsin.
#2 Oregon likes to toy around with their opponents before putting them away and their game at Washington State followed the script perfectly. They led Wazzu 15-14 after 1Q before pulling away, 43-23. The Ducks host UCLA this weekend.
#3 BSU dispatched Toledo 57-14 with ease and will travel to San Jose on Saturday for a WAC contest vs. a Spartan program that has never defeated the Broncos. Ho-hum.
#4 The Cornhuskers rolled over previously undefeated Kansas State last Thursday night in Manhattan, 48-13. Nothing is more important on Nebraska’s list of goals this season than to beat Texas and they’ll get their chance to do that this weekend in Lincoln.
#5 The Sooners had a bye last weekend and host a battered Iowa State Cyclone squad this week.
#6 Texas Christian tossed another shutout in Mountain West Conference play, smacking down Wyoming, 45-0. They stand a good chance of pitching their third straight skunk when an uncharacteristically anemic BYU offense comes to Fort Worth on Saturday.
#7 Alabama suffered their first loss since the 2009 Sugar Bowl — this time to a very good South Carolina team, 35-21. The Tide begin their ascent back up the charts when they host Mississippi this weekend.
#8 Auburn traveled to Lexington last Saturday and the Tigers escaped with a 37-34 win over a scrappy Kentucky Wildcat team. They host #10 Arkansas this week.
#9 Louisiana State University notched a signature victory over Florida at The Swamp and their reward is a breather game against Division 1-AA McNeese State this Saturday. They’ll need it because they face Auburn and Alabama the following two weeks.
#10 Arkansas dropped a few notches after a close 24-17 win over Texas A&M. They head on the road again this weekend to take on #8 Auburn in one of the biggest games of the week.
#11 Iowa had a bye last weekend. Next: at #22 Michigan. If they can contain Denard Robinson and leave Ann Arbor with a win this Saturday, they’ll be in the thick of the Big Ten title mix for weeks to come. A loss would practically doom their Rose Bowl dreams.
#12 The Spartans now reign throughout the state of Michigan after a dominating win over the Wolverines in Ann Arbor, 34-17. They’ll need to be on guard with a dangerous Illinois team visiting East Lansing this weekend.
#13 If any Pac-10 team has USC’s number, it’s Stanford. Under Jim Harbaugh, the Cardinal have defeated the Trojans three out of the past four years. Their latest W came Saturday night on a last second FG, 37-35. Next: Washington State in Palo Alto.
#14 The Gamecocks knocked off #1 Alabama and look like a legitimate contender for the SEC crown this season. Next game: at Kentucky this Saturday.
#15 The Badgers took care of some Big Ten business and retained ownership of the Paul Bunyan Axe with their victory over rival Minnesota. You know they’ll be rolling out the Big Red Welcome Carpet for #1 Ohio State this Saturday.
#16 The Utes thrashed Iowa State 68-27 in Ames and head out on the road again this weekend to Laramie to face vs. a battered Wyoming Cowboy team.
