College Football Rankings 2013: Top-25 Teams That Will Fall in Week 5

A grand total of one Top-25 team fell in Week 4 of the 2013 college football season.

With several Top-25 teams facing off in Week 5, expect things to be different.

We have some high-octane battles in Week 5, including Ole Miss vs. Alabama, Wisconsin vs. Ohio State and Oklahoma vs. Notre Dame.

Alabama is still the No. 1 team in the nation, in case you hadn't noticed.

Meanwhile, Buckeyes backup quarterback Kenny Guiton has exploded in place of injured starter Braxton Miller. 

But who will meet their match in Week 5?

Read on.

Ole Miss 

Ole Miss may have landed the No. 8 recruiting class in the nation this year, according to 247Sports.com, but many thought it would take at least a year for Hugh Freeze and the Rebels to make a significant impact. 

All Ole Miss has done is start the season 3-0, including a 44-23 victory over Texas on Sept. 14.

Unfortunately for the young Rebels, they have to face No. 1 Alabama next Saturday...in Tuscaloosa.

Good luck.

Nick Saban once again has Alabama up in front of the rest of the nation. Seeking their third consecutive national championship, the Crimson Tide have won their first three games of the 2013 campaign, including a 49-42 thriller over Johnny Manziel and Texas A&M on Sept. 14 in College Station.

There are some concerns about Alabama's secondary after allowing 42 points to the Aggies. Saban has said as much, per Alex Scarborough of ESPN.com.

Heck, there are concerns about Alabama's entire defense. 

On top of that, starting cornerbacks Deion Belue and Jarrick Williams—as well as safety Nick Perry—missed the matchup against Colorado State in Week 4, due to injury.

But this is still Alabama we're talking about, playing at home. Last season, the Crimson Tide uprooted the Rebels in Tuscaloosa, 33-14.

It's only a matter of time before the Tide get rolling, and the Week 4 breeze against Colorado State may have helped Alabama recover a bit (literally and figuratively) from the shootout in College Station.

Wisconsin

Wisconsin has had no trouble rolling over inferior opponents Massachusetts, Tennessee Tech and Purdue this season, but the Badgers lost to Arizona State in Week 3.

Yes, the Badgers could have defeated the Sun Devils on Sept. 14 if not for the confusion in the closing seconds, but it's also worth noting that Gary Andersen's squad surrendered 468 total yards of offense in the 32-30 loss.

Wisconsin faces Ohio State next Saturday in Columbus. This is the same Ohio State that has exploded for 210 points in its four games. The Buckeyes annihilated Florida A&M in Week 4, 76-0...with their backup quarterback.

While Braxton Miller has been recovering from a sprained MCL in his left knee the past two games, backup Kenny Guiton—who had 25 pass attempts coming into the season—has ripped defenses apart. 

In his last two games as starter against Cal and Florida A&M, Guiton has gone a combined 45-of-66 for 491 yards, tossing 10 touchdowns to one interception in the process.

He went 24-of-34 while tossing six touchdowns to one interception against the Rattlers on Saturday. He rushed for 92 yards against the Golden Bears, showing off dual-threat ability.

Whether Wisconsin faces Miller or Guiton on Saturday doesn't matter. What matters is that no one has been able to stop the Buckeyes this season, and the Badgers will be no different.

Notre Dame

Notre Dame edged Michigan State on Saturday at home, 17-13, but it certainly wasn't pretty.

Beyond that, the Fighting Irish have taken care of easy opponents Temple and Purdue, while losing to Michigan, 41-30.

That loss to Michigan has me worried for Notre Dame against upcoming opponent Oklahoma.

Notre Dame's offense and defense have taken a step back in 2013 after several key losses in the offseason, including quarterback Everett Golson (at least temporarily) and linebacker Manti Te'o.

The Fighting Irish gave up 41 points to Michigan after defeating the Wolverines last season, 13-6. Then they gave up 24 points to Purdue the following week (a season-high for a team currently averaging 15.3 points per contest).

Brian Kelly's squad may limit Oklahoma's offense on Saturday, but I'm more concerned about Notre Dame's offense against a Sooners unit that has allowed 9.0 points per game this season.

In the 17-13 victory over the Spartans in Week 4, quarterback Tommy Rees came back down to earth, going 14-of-34 for 142 yards with a touchdown, while Notre Dame's running game continued to flounder, totaling 78 yards on 32 carries.

Notre Dame's rushing "attack" isn't good enough to do damage against the Sooners. Neither is its passing attack.

Expect a loss for the Fighting Irish when Oklahoma comes to town.
