Several people have asked why I have Villanova No. 1.

My answer: The Wildcats have the nation's best resume, plain and simple. Villanova is 17-1 with four top-25 KenPom wins and six top-50 victories -- two of which came in true road games. None of the other obvious candidates for No. 1 -- i.e., UCLA, Kansas and Gonzaga -- can match that. And Villanova's lone loss is a single-digit loss on the road to a Butler team I have ranked ninth, which is comparable to UCLA's loss (at Oregon) and better than Kansas' loss (to Indiana).

So that's why Villanova is No. 1 in the Top 25 (and one).

And I imagine the Wildcats will stay there until/unless they lose again.
