It's a parade of No. 1 seeds along the Riverwalk in San Antonio as the men's NCAA Tournament is down to its Final Four. See the matchups, schedule.

The Trojans, despite losing star JuJu Watkins to a season-ending injury earlier in the tournament, managed to survive their Sweet 16 matchup against Kansas State. But UConn will provide a much stiffer test.
