Since 2002, just one national title winner failed to finish in the Top 25 in both Adjusted Offense AND Adjusted Defense on kenpom.com. That was UConn in 2014 who finished 39th in AdjO and 10th in AdjD. Carolina in 2009 was the only other team in that span to fail to finish in the Top 20 in both (1st in AdjO and 21st in AdjD).
As of now, this years group of teams in the Top 20 in AdjO-AdjD are the following:
Oklahoma: 15th-2nd
Louisville: 20th-3rd
Xavier: 19th-6th
Kansas: 11th-8th
Michigan State: 9th-11th
Villanova: 10th-13th
Virginia: 2nd-15th
Dropping it down to Top 25 in both would add:
Kentucky: 22nd-12th
History says one of those teams wins in April.
