The Southeastern Conference was sort of a no-show in Week 1. The league with 13 of the last 17 national championships went 0-3 in marquee matchups. Florida, South Carolina and LSU each lost by double digits in primetime, non-conference games. The trio got dumped by a combined 48 points and showed significant flaws in their season openers. The SEC gets a chance to redeem itself in Week 2 showdowns featuring No. 3 Alabama, No. 20 Ole Miss and No. 23 Texas A&M. The Tide host 11th-ranked Texas. The Rebels play at No. 24 Tulane. And the Aggies travel to Miami.

An overhaul on Atlantic Coast Conference coaching staffs this offseason has left some teams struggling to adapt to to new systems. There are eight new offensive coordinators in the ACC this season — more than half of the league. Some ACC teams made changes to shore up offenses that were slipping; others had to replace coaches who left for better jobs. Clemson fired offensive coordinator Brandon Streeter after just one full season as the offensive play-caller and hired Garrett Riley away from Texas Christian, where he helped the Horned Frogs reach the national championship game. Coach Dabo Swinney didn't get the improvement he hoped for in a 28-7 loss to Duke that dropped the Tigers from No. 9 to No. 25 in The Associated Press Top 25.

The Week 1 result that seems really meaningful but turns out not to be is a time-honored tradition in college football. The gold standard of this category is the infamous "Texas is back" game in 2016 when the Longhorns beat Notre Dame in overtime. The teams finished a combined 9-15. No. 21 Duke and No. 22 Colorado rode big upsets in high-profile games this past weekend to spots in the first regular-season AP Top 25 of the season Tuesday.
