After two weeks of buzzer beaters, upsets and standout performances, we've reached the Final Four: the North Carolina Tar Heels, Gonzaga Bulldogs, South Carolina Gamecocks and Oregon Ducks are headed to Phoenix.
North Carolina is appearing in the Final Four for the 20th time, the most of any team in NCAA tournament history. It's also the second consecutive Final Four appearance for the Tar Heels, who fell to the Villanova Wildcats in last year's national title game.
As for the other three teams in the Final Four, only one has been before: Oregon in the inaugural NCAA tournament in 1939.
