There are no words to describe the chaos that we witnessed last week.

Some of the country's best teams were put to the test, and a few of those teams found themselves on the losing end of an upset. Here is a quick recap of the chaotic weekend just in case you missed any of the action:

  • Utah traveled to Autzen Stadium and demolished Oregon by a final score of 62-20. It was Oregon's worst loss since 1985.
  • TCU needed to catch a tipped pass on 4th and goal to avoid being upset by Texas Tech. The Horned Frogs survived, 55-52.
  • Texas A&M also avoided a catastrophe, but they needed a few extra minutes to do it. The Aggies won 28-21.
  • Ole Miss got more than they expected from Vanderbilt, and the Rebels barely escaped with a 27-16 win.

Week five has all the makings for another hectic week, so here are three games that we think you should keep an eye on if you are wanting to see an upset.

  • #23 West Virginia at #15 Oklahoma

    Line: Oklahoma -7

    It comes as no surprise that both West Virginia and Oklahoma enter this weekend's game undefeated. What is surprising is that the Mountaineers have put together a pretty good defense to go along with their potent offense. This could be a sign of trouble for the Sooners.

    Granted, West Virginia has not yet faced a quality offense, but the defense has performed well. The Mountaineers have the best scoring defense in the Big 12 and only allow 154 passing yards per game. This will come in handy when facing a talented passer like Baker Mayfield. Combine West Virginia's improved defense with their balanced offense and you have a recipe for a road upset.

    Oklahoma has plenty of talent of their own. The Sooners feel confident knowing that Mayfield would lead just about any other conference in passing, and running back Samaje Perine is not too shabby either. Mental errors appear to be the only thing that will slow down this team. They have the worst turnover margin in the conference, and they are also one of the most penalized teams in the conference. Those two things alone can cost you.

    West Virginia faces the tough challenge of trying to take out Oklahoma on the road. However, the Sooners are 3-3 in their last six home games, and they were favorites to win all six games. Keep an eye on this one.

  • #3 Ole Miss at #25 Florida

    Line: Ole Miss -7.5

    Florida showed great resiliency in last week's win over Tennessee. The same can be said about Ole Miss. The only difference being that the Rebels were expected to blow out their opponent. Will that trend continue in Gainesville?

    Opinions on Florida in the preseason varied. McElwain has proven that he may not need as much time to compete in the SEC East as expected. Florida has not done anything eye-popping, but they certainly rise to the occassion. The defense, led by Jonathan Bullard, comes up in when it matters most, and the offense is playing with much more consistency compared to last year's numbers.

    It is probably unfair to look too much into Ole Miss' performance against Vanderbilt. The Rebels were coming off of a big win over Alabama, so it is safe to say that they may have played "hungover." It is fair to say that Florida will take advantage if Ole Miss plays like that again. The Rebels will still be tough to stop. The offense is one of the best in the SEC, and the defensive front seven is a force to be reckoned with.

    This game could end with a big upset for Florida or it could end in convincing fashion for Ole Miss. The Gators have not a played a team with the same level of talent, so it will be interesting to see how well they compete against the experienced Rebels.

  • #1 Ohio State at Indiana

    Line: Ohio State -21

    Your jaw may have already hit the floor before you even read this sentence. Saying that Indiana could upset the number one team in the country appears to be a bit of a stretch, but you will soon find out that it is actually within the realm of possibility.

    If Indiana is going to beat Ohio State then this is the year to do it. UAB transfer Jordan Howard leads the conference in rushing, and the Hoosiers, not the Buckeyes, currently have the best total offense in the Big Ten. They will face a stingy defense, but they will put up points. However, Indiana has to fix some of their defensive issues before Saturday. They are currently dead last in the conference in total defense.

    Ohio State has already survived a few upset scares this season. That comes with the territory of being the number one team in the country. The Buckeyes' defense has bailed them out when the offense was not performing up to par. Cardale Jones and J.T. Barrett have both thrown as many interceptions as they have touchdowns and both are completing less than 60 percent of their passes.

    Indiana fans are excited about being given an opportunity to turn Memorial Stadium into a hostile environment. Ohio State could put this one out of reach early, but just know that the Hoosiers have enough talent to make this one close.
