These teams are rather familiar. They're not as well-acquainted as their fellow Final Four participants, but No. 1 Kansas and No. 2 Villanova have run into each other three times en route to national titles in the last 15 years.
In 2018, No. 2 Villanova beat No. 4 Kansas in the Final Four to advance to the national title game, which it won against No. 3 Michigan. And two years before that, No. 2 Villanova defeated No. 1 Kansas in the Sweet 16 a few rounds before its epic championship win against No. 1 North Carolina.
