Texas is No. 1 in the AP Top 25, and it got there the hard way: by erasing a 20-point hole against Ohio State in Austin in what the reporting out of Texas is calling an unprecedented comeback. The poll came out Sunday, the Longhorns went to the top, and the Buckeyes fell out of the top five for the first time in two seasons. Oregon slid too. One Saturday afternoon, and the whole top of the sport got rearranged.

That is the part I keep chewing on. Not that Texas won, but that Texas won from 20 down, at home, against the program that had spent two years as a permanent fixture in the top five. Comebacks like that do something to a locker room that a comfortable win never does.

Why is Texas No. 1 in the AP Top 25?

Because voters reward the moment, and this was the moment. A head-to-head result against the team that had been carrying the sport's highest floor is the cleanest resume line available in September, and Texas now owns it. The AP poll has always been a human instrument, which is its charm and its flaw: it watches the fourth quarter and it remembers how the fourth quarter felt.

What the ballot cannot tell you is whether the Longhorns played like the best team in the country for sixty minutes or for twenty of them. From 20 down, the honest answer is probably the second one. That is not a knock. Teams that can win a game they were losing badly tend to be teams with something in the tank that does not show up in a box score.

Why does ESPN's FPI still have Ohio State at No. 1?

Here is where it gets genuinely fun. The same weekend that dropped Ohio State out of the AP top five, ESPN's FPI moved the Buckeyes up to the top spot. Not down. Up. The metric weighs the body of work and the underlying efficiency rather than the scoreboard's final mood, and by that accounting a team that built a 20-point lead on the road against a top opponent still profiles as the strongest roster in the country.

You can argue that both things are true at once. The humans are grading the ending. The model is grading the first three quarters and the talent that produced them. Ohio State's problem is that only one of those two gets to hand out a trophy in January.

checked the almanac: the ap poll has been ranking college football teams since 1936, and nine decades in, a single afternoon can still knock the sport's most stable program out of the top five.

What comes next for Texas, Ohio State and Oregon

For Texas, the challenge is the one that always follows a signature win: not deflating. Programs that pull off something they will show on a highlight reel for twenty years have a nasty habit of playing flat the following week. That is the tell I want to watch for.

For Ohio State, the internal message writes itself, and the FPI number actually helps: the film says you were the better team for most of an afternoon. The finishing did not hold. That is a coachable failure, which is better than a talent failure.

Oregon's tumble is the quieter story of the weekend, and it deserves its own look once the rest of the week's reporting fills in.

There is one more thread worth pulling. One of the sport's lead broadcasters, working both the U.S. Open in New York and the game in Austin, spent part of the week calling weak nonconference scheduling "a joke." He called it from the booth of the exact game that proves his point. Texas and Ohio State scheduled each other, and the sport got its best afternoon of the young season out of it. Everyone else scheduled a tune-up.

What I am watching next: whether Texas holds up to the week of being No. 1, how Ohio State answers in its next meeting with real competition, and whether the AP voters and the models stay this far apart once the sample grows. Right now they are describing two different sports.
