It wasn't like watching No. 1 Kentucky lose to Evansville or like watching No. 1 Duke lose to Stephen F. Austin -- or even like watching No. 1 Louisville lose to a Texas Tech team that was missing its best player. Those were all major surprises; what happened Saturday was not. But, still, the No. 1 team has indeed lost again. This time it was No. 1 Kansas losing 56-55 at Villanova.

"It's just one of those years," said Villanova coach Jay Wright. "There just isn't one team that's dominant."

Those are true words.

As I've explained before, the fact that top-ranked teams keep losing isn't the only indicator that dominant teams don't exist this season. It's also apparent when studying adjusted efficiency margins. Right now, according to KenPom, Ohio State has an adjusted efficiency margin of +27.69 that ranks No. 1 nationally. But +27.69 would've only tied for seventh nationally last season -- and what that means, in the simplest of terms, is that this season's best teams aren't as good as the best teams we're used to watching. In fact, if +27.69 were to finish as the best adjusted efficiency margin this season, it would be the lowest final best adjusted efficiency margin of the KenPom era that dates back to the 2001-02 season.

So keep that in mind going forward because it is the top explanation for why highly ranked teams keep losing to lower-ranked and unranked teams. And it's also why there's a new No. 1 in  Sunday morning's updated CBS Sports Top 25 And 1 daily college basketball rankings -- and the new No. 1 is Ohio State.

The Buckeyes, 11-1 after Saturday's win over Kentucky, are the only zero-loss or one-loss team with four top-40 KenPom victories -- among them a 25-point blowout of the nationally ranked Villanova team that just beat Kansas, a 32-point blowout of the nationally ranked Penn State team that's beaten Maryland, and a 25-point blowout of the North Carolina team that's beaten Oregon. Beyond that, the Buckeyes are No. 1 at KenPom. And Ohio State's lone loss came last weekend at Minnesota when the Buckeyes were missing their second-leading scorer (Duane Washington) because of a rib injury -- which means Ohio State has better wins than anybody with a comparable loss column, and the lone loss was a shorthanded loss in a road game. So, in my opinion, Ohio State has the nation's best body of work.

Feel free to argue about it on Twitter, though.

Let the record show that Villanova, Butler and San Diego State all recorded impressive wins Saturday and jumped into the top 14 of Sunday morning's Top 25 And 1 -- which pushed Maryland, Florida State and Washington down, no fault of their own. Meantime, Arizona and VCU both lost to unranked opponents and were removed from the Top 25 And 1. They've been replaced by West Virginia and Wichita State.
