The first full week of the 2023 college football season is in the books, and we saw exactly what we expected: The unexpected.

Between teams getting upset or just not playing up to their standards, this Week 2 of the season will go a long way in determining which teams are legit and which aren't. 

Today, let us take you through our top storylines to follow in CFB Week 2.

Is Duke for real or is Clemson overhyped?

The Clemson Tigers have been one of the nation's top programs over the past decade or so, but it seems like the tide is shifting on Dabo Swinney's ball club. 

The Tigers suffered three losses last season and then opened up the 2023-24 campaign with a 28-7 loss at the hand of the Duke Blue Devils. Clemson dropped from no. 9 to no. 25 in the latest AP Poll, and will now get the chance to right the ship this week against Charleston Southern.

Clemson may not be what they once were, but this Duke team deserves a lot of credit as well. 

Quarterback Riley Leonard stole the hearts of college football fans across the US and at this early stage, he appears to be one of the top signal callers in the country this season. 

After some abysmal years as a program, Duke head coach Mike Elko has this squad destined for big things. They'll face Lafayette this weekend ranked as the no. 21 team in America.

LSU needs a big rebound week

In another disappointing performance from a top 10 team, the LSU Tigers were pretty much embarrassed against Florida State in primetime on Sunday night. 

The Tigers lost by three touchdowns in a game that they were dominated in from almost all facets. That outing dropped LSU all the way from no. 5 in the AP Poll to now just at no. 14.

Fortunately for Tigers fans, this weekend presentes a perfect opportunity to get things back on track. 

They'll play in their home opener against Grambling State, which they should be able to dominate from start to finish. The season isn't over for LSU by any means, but they'll certainly need to look sharper than they did last time out.

Buckeye fans want more from Ohio State

Ohio State actually came away victorious in their season opener, and by quite a significant margin (20 points). 

The Buckeyes went on the road to begin this campaign and handled Indiana, although it wasn't quite the dominating performance that they had hoped for and expected. 

OSU was just 2/12 on third downs as an offense and failed to produce a passing touchdown.

While the ground game was dominant, the quarterback play in this post-C.J. Stroud era was a bit concerning, especially with huge talents like Marvin Harrison Jr. and Emeka in the receiving corps.

They played poorly enough to be knocked down two spots in the AP Poll to no. 5, and even though they should roll over this week's opponent in Youngstown State, they have a much-anticipated date scheduled with Notre Dame in less than a month.

Quarterback Kyle McCord will want to prepare for the Notre Dame game with a string of strong performances.

Can Colorado keep the good times rolling?

One of the biggest storylines from College Football Week 1 was the Colorado Buffaloes and new head coach Dieon Sanders. 

They went into TCU's stadium and defeated the Horned Frogs 45-42 thanks to the stellar play from Sanders' son, Shadeur, at QB and two-way star Travis Hunter making plays at both CB and WR.

The Buffaloes have a brutal schedule though, and things don't get any easier this week as they'll play host to Matt Rhule's Nebraska Cornhuskers. 

While Nebraska isn't a powerhouse these days, they surely have some solid players and played well despite losing to Minnesota last time out. Whatever happens, all eyes are sure to be on Colorado again this week.

The Buffaloes are favored by -3.0, and Nebraska is +135 on the money line with a 59.5 O/U.

Potential upset alerts for CFB Week 2

Most of the nation's top teams took care of business in Week 1, but there were still plenty of upsets that played out. Wyoming over Texas Tech, Fresno State over Purdue, Northern Illinois over Boston College and Texas State over Baylor all caught the attention of college football fans.

This week, while it may be difficult to pinpoint exactly which matchups, there will surely be more upsets again. 

Texas Tech vs. Oregon (-6.5), Cincinnati vs. Pittsburgh (-7.5), Notre Dame (-7.5) vs. NC State and, of course, Texas vs. Alabama (-7.0) are all games that come to mind regarding possible Week 2 upsets.
