When choosing best non-conference game, a matchup can only be used once. So even though it includes teams from two Power 5 leagues, it will only be mentioned once. So don't be angry if it's listed in one place but not another.
Of course, once the season begins all of this will change. The schedule that looked intimidating will turn out to be a dud, while the one that was laughed at will suddenly look formidable.
Here is a breakdown of all of the Power 5 conference non-league schedules:
ATLANTIC COAST CONFERENCE 
It's apparent that the league feels Notre Dame is a de facto member, even though it went back to its Independent status after the COVID season of 2020. Five ACC squads will play the Fighting Irish in 2023, including 2022 Irish victim Clemson. Tennessee, Texas A&M, Florida, South Carolina and Cincinnati dot ACC schedules, which on the whole are not terrible. UConn appears on three ACC slates, while Old Dominion will face a pair of league teams.
Kudos to Florida State, which has LSU and Florida as bookends on its schedule, and a home contest against Southern Miss that may not be the cakewalk everyone expects.

Quite often the poster child of exemplary non-league scheduling, the Big Ten this year has really dumbed things down. Seven teams have scheduled FCS opponents, one has zero Power 5 foes and just one faces two teams from a Power 5 league. Bravo, Big Ten -- you've stopped pretending that you at least wanted to be challenged in the early portion of the season. Now it's simply a walkthrough.

Much like the Big Ten, the Big 12 isn't doing much to strain itself during the non-league portion of the schedule. Only two teams aren't facing an FCS foe, and many aren't even leaving their home state in September. There is the marquee matchup of Texas at Alabama, and a couple of other intriguing contests (Utah at Baylor, Colorado at TCU and West Virginia at Penn State and home to Pitt), but there aren't a whole lot of "wow, that's a doozy!" occasions on the 2023 slate.
Bonus points to new member Houston, which plays only in-state non-league games, and soon-to-be-departing staple Oklahoma, which makes the grueling two hour drive to Tulsa but otherwise has the comforts of home early in the season. Nice job, guys.

If the Pac-12 is going away -- and that looks to be the case given the panic that has set in among admins trying frantically to get a television deal -- at least it will go down swinging.
Numerous league teams have taken it upon themselves to schedule premier out of conference matchups, so there will be plenty of chances for attention in 2023. Three teams have even decided to schedule only FBS teams, which is a victory itself. Utah and USC will be tested this season, and Coach Prime will also have time in the spotlight as his Buffs face CFP participant TCU right out of the box.

While there definitely are some intriguing matchups in the SEC, most of it is the usual lower-rung cannon fodder that dots schedules each season. The obligatory FCS game -- almost always late in the season -- is still there, and there seems to be even more detail paid to putting Group of Five teams that finished near the bottom of their conference on the slate.
Special mention goes to Auburn, which has UMass, maybe THE worst team in FBS, Cal, which won four games last season and may not be much better this season, and New Mexico State, which is perennially bad but had a resurgence under Jerry Kill and won seven games in 2022. At least their FCS foe, Samford, was a top 10 team.
