Check out and listen to the top plays and sounds from Week 2 of the college football season, including Arkansas's upset of TCU, Central Michigan's Hail Mary to beat Oklahoma State and highlights from Tennessee's game at Bristol Motor Speedway. (1:42)

It was supposed to be an easy week, and for the most of the Top 25 it was, but whether is defeat or close victory, several teams looked really shaky against inferior competition. Take a look at how it all shook out in our Power Rankings.

Week 2 result: Defeated Western Kentucky 38-10

Like an inexorable force of nature, Alabama casually rolled over Western Kentucky, setting up a key SEC West showdown with Ole Miss. While the Rebels are on their heels after losing their opener to Florida State, they own something that almost seems miraculous: a winning streak against Nick Saban. Ole Miss has won the last two games in this series, which officially makes the Rebels the Crimson Tide's nemesis.

Week 2 result: Defeated Charleston Southern 52-8

After having little trouble with Charleston Southern, the Seminoles turn their attention to Louisville and the Lamar Jackson Show. Or will that be the Deondre Francois Show, counters FSU? This ACC clash features two impressive young gunslingers vying to push their teams to the top of the ACC -- at least until they meet Clemson.

Week 2 result: Defeated Tulsa 48-3

The Buckeyes started slowly but ultimately dominated Tulsa in a 48-3 victory, with the defense playing lead and the offense catching up with a rugged running game. J.T. Barrett and the passing attack? Well, we'll see -- and soon -- as Ohio State heads to Oklahoma on Saturday for a critical matchup between teams with CFP aspirations.

Week 1 ranking: 5

Week 2 result: Defeated Lamar 42-0

No Greg Ward Jr.? No problem. Houston crushed Lamar by running the ball against an overmatched foe, but the bigger issue is whether Ward will be 100 percent at Cincinnati on Thursday with a short week of preparation. Ward sat out with an injury to his right throwing shoulder. While the school reported no structural damage, the question remains whether this could be a nagging issue on a week-to-week basis, affecting Ward as both a passer and runner.

Week 2 result: Defeated Troy 30-24

While Clemson's 30-24 win over Troy wasn't pretty, it was a win and survival is the name of the game in this already slightly nutty season. Is the offense a concern? Perhaps. A matchup with South Carolina State should provide another chance for Deshaun Watson & Co. to iron out some persistent wrinkles before the ACC slate starts at Georgia Tech on Sept. 22, a Thursday night showdown in Atlanta.

Week 1 ranking: 6

Week 2 result: Defeated UCF 51-14

After mowing over Central Florida, the Wolverines might face their first challenge of the season during a visit from a seemingly improved, 2-0 Colorado squad. Michigan was churning on both sides of the ball against the Knights, with new starting QB Wilton Speight turning in a highly efficient performance.

Week 1 ranking: 7

Week 2 result: Did not play

The Cardinal enjoyed a bye after taking down Kansas State in Week 1, but a visit from USC at the very least should be interesting as the Trojans should be highly motivated to rehabilitate their national image after getting trounced by Alabama in Week 1. While the Cardinal beat the Trojans twice last year -- in the regular season and Pac-12 championship game -- USC won the previous two meetings.

Week 1 ranking: 8

Week 2 result: Defeated Idaho 59-14

The Huskies continued their jaunt through a pillow-soft nonconference schedule with a blowout of hapless Idaho. While the Huskies have taken care of business like a top-10 team playing weak foes, we won't know much about them until they open the Pac-12 slate at Arizona and thereafter play Stanford and Oregon back-to-back. Up next? Portland State, an FCS team.

Week 1 ranking: 10

Week 2 result: Defeated Akron 54-10

The Badgers didn't let up after their red-letter win over LSU, whipping Akron 54-10, rolling up 586 yards on offense and holding the Zips to just 10 first downs. Wisconsin plays host to Georgia State next weekend and then gets Big Ten play rolling on Sept. 24 at Michigan State, a potential separation game in the conference pecking order.

Week 1 ranking: 12

Week 2 result: Defeated Syracuse 62-28

Cardinals quarterback Lamar Jackson announced himself as a Heisman Trophy candidate with five touchdowns -- four rushing -- and an ACC record 610 total yards in a 62-28 win over Syracuse. He can push his candidacy to another level if he can beat No. 3 Florida State and transform the preseason ACC and CFP picture.

Week 1 ranking: 11

Week 2 result: Defeated UTEP 41-7

The Charlie Strong renaissance continued with the Longhorns whipping UTEP 41-7, a four-quarter domination. Despite a number of O-linemen sitting out due to injury, freshman QB Shane Buechele completed 22 of 27 for 244 yards with four touchdowns and no interceptions and he rushed for 34 yards for good measure. Up next is an interesting matchup at California.

Week 2 result: Defeated Virginia Tech 45-24

Tennessee was down 14-0 to Virginia Tech in the first quarter, and you could already see the sports writers lining up for the "2016's Biggest Bust" stories. Then ... poof! The Vols found their mojo and looked like the SEC East favorite they are supposed to be, rolling up 31 unanswered points before the Hokies managed to answer with a field goal. The Vols now host Ohio before beginning their SEC gantlet: Florida, Georgia, Texas A&M and Alabama.

Week 2 result: Did not play

The Spartans took the week off in advance of their trip to Notre Dame, the first test of the season for new starting QB Tyler O'Connor. The Spartans won three straight over the Fighting Irish from 2011-13.

Week 1 ranking: 15

Week 2 result: Defeated Prairie View 67-0

Aggies QB Trevor Knight piled up some nice numbers passing and running against Prairie View, but can he do the same at Auburn, which mostly corralled Clemson QB Deshaun Watson? The Aggies can make an early SEC West statement and perhaps further embolden the gathering calls for Tigers coach Gus Malzahn's job.

Week 1 ranking: 17

Week 2 result: Defeated Louisiana Monroe 59-17

The Sooners blasted Louisiana Monroe, perhaps ridding themselves of the residual bad taste of the opening loss to Houston. If there is any remaining -- and there probably is just a bit -- they can thoroughly cleanse it by figuring out a way to beat Ohio State on Saturday. A marquee win like that would certainly put Oklahoma back into the CFP contender track.

Trending:

Week 1 ranking: 16

Week 2 result: Defeated Nevada 39-10

The Fighting Irish stomped Nevada 39-10, showing no signs of a hangover after losing a heartbreaker to Texas in Week 1. On the downside, cornerback Shaun Crawford suffered an Achilles injury that will sideline him for the season, and the Irish secondary already has injury and suspension issues. Up next is a visit from Michigan State, a game that can put the Irish back on the CFP map. Or knock them out for good.

Week 2 result: Defeated Iowa State 42-3

The Hawkeyes, who've been all over the place in their rivalry with Iowa State, dominated the Cyclones from bell-to-bell, with QB C.J. Beathard particularly efficient. When you look at Iowa's schedule, it's difficult to believe the Hawkeyes won't reach an Oct. 22 date with Wisconsin at 7-0.

Week 2 result: Defeated Nicholls 26-24

Good golly, Mr. Smart, what the heck was going on against Nicholls? Oh, well, a win is a win -- we guess -- even if it's just 26-24 against a 55-point underdog. Obviously, touted true freshman QB Jacob Eason isn't going to provide immediate magic to the offense. A visit to Missouri didn't seem very daunting a week ago, but the Bulldogs apparently can't take anyone lightly.

Week 1 ranking: 14

Week 2 result: Defeated Wofford 38-13

While Ole Miss' win over Wofford wasn't artful, it did help put some distance between the Rebels and a tough opening loss to Florida State. And all those frowns in Oxford will turn upside down if Ole Miss can win a third straight over Alabama, the nation's defending national champion and current No. 1 team.

Week 1 ranking: 22

Week 2 result: Defeated Jacksonville State 34-13

While LSU's 34-13 win over Jacksonville State was far from pretty -- and didn't include an injured Leonard Fournette -- it appears that the Tigers have found a quarterback, as Danny Etling, a Purdue transfer, came on for the ineffective Brandon Harris and led the Tigers to all their points. Of course, Jacksonville State is one thing. A visit from Mississippi State is another.

Week 1 ranking: 25

Week 2 result: Defeated Virginia 44-26

Oregon owned a struggling Virginia squad, with the offense looking flashy and the defense looking ... well, better. We'll get a much more substantive measure of whether Oregon is a legit Pac-12 North Division contender again after a trip to Nebraska on Saturday. The Cornhuskers sideline will look familiar with former Oregon State coach Mike Riley leading Big Red.

Week 2 result: Defeated SMU 40-13

Baylor didn't look like itself in the first half against SMU -- it failed to score a TD before the break for only the fourth time in its past 57 games -- but it surged in the third quarter and coasted home. The Bears' annual preseason of cupcakes when the rest of college football is playing tough nonconference games continues next Friday at Rice.

Week 2 result: Defeated TCU 41-38 (2OT)

The Razorbacks looked much better in Week 2, showing good offensive balance in their double-overtime win at No. 15 TCU. More than that, they showed some mental toughness by overcoming the Horned Frogs' fourth-quarter comeback to prevail in OT. After a visit from Texas State, a more dangerous Texas team comes to town -- Texas A&M -- in a potentially significant SEC West showdown.

Week 1 ranking: NR

Week 2 result: Defeated Kentucky 45-7

The Gators blasted woeful Kentucky and looked good on both sides of the ball while doing so, owning a 564-149 yardage advantage in a 45-7 domination. Of course, Florida's early season is littered with patsies, including a visit from North Texas on Saturday, so we won't get a true measure of the Gators until they visit Tennessee on Sept. 24.

Week 2 result: Defeated UNLV 42-21

UCLA started quick, meandered and then pulled away from UNLV in a 42-21 victory, but the bigger issue may be the health of defensive tackle Eddie Vanderdoes, by far the Bruins' best defensive player. He didn't play in the second half with what was called a "strained" right knee. Vanderdoes missed all of the 2015 season after he blew out his left knee. The Bruins visit BYU on Saturday.
