With the college basketball season starting Nov. 6, we asked NCAA.com basketball expert Andy Katz to fill out a March Madness bracket based on everything he saw this preseason.

We’ll break down his picks, but first, let’s take a look at Andy’s bracket:

There are definitely some interesting choices in there. Let’s break them down. 

Here’s the field Katz predicts:

Seed South East Midwest West
Kentucky Duke Kansas Gonzaga
2 Nevada Tennessee North Carolina Virginia
3 Syracuse Kansas State Auburn Michigan State
4 Florida State Villanova Nebraska West Virginia
5 Purdue UCLA Marquette Washington
6 Michigan Indiana UCF Loyola Chicago
7 Virginia Tech Clemson Oregon Mississippi State
Cincinnati TCU Wisconsin Minnesota
Butler Davidson Buffalo Providence
10  Alabama St. Louis Florida Iowa State
11 St. John’s LSU Texas Houston
12  Georgetown/USC Harvard St. Joseph’s/Memphis Marshall
13  Wofford Northeastern Rider South Dakota State
14  Georgia State Grand Canyon Belmont Stephen F. Austin
15  Montana UC Davis Wright State Lehigh
16  Lipscomb/Winthrop FDU/Bethune-Cookman Grambling Vermont

Now let’s take a closer look:

Andy’s Final Four: Kentucky, Villanova, North Carolina and Gonzaga

Katz has what would be a thrilling lineup here, with a 2017 championship game rematch in UNC vs. Gonzaga in the semifinal, and the potential for a 2016 championship game rematch with UNC and Villanova in the title game. That UNC-Gonzaga game will also be a rematch of a regular season game this year, as the Bulldogs are scheduled to travel to Chapel Hill on Dec. 15.

On the other half of the bracket is a Wildcat showdown. Fun fact, since 2011, there has been a Wildcat team in the Final Four in all but two years (2013 and 2017). Each of those has been Kentucky or Villanova. In total, those two Wildcats have been in seven Final Fours since 2009, but never in the same year. 

Best upset picks: Marshall and Iowa State

12-seed Marshall over 5-seed Washington
