Dayton and VCU met as the teams expected to be here when the season began.
The Rams were picked to repeat as Atlantic 10 regular season champions with Dayton No. 2, but the Flyers won the league by two games to secure the No. 1 seed while VCU settled for second.
Dayton advanced to the A-10 championship game for the first time since winning it in 2017. The Flyers also won the 2012 tournament.
VCU lost the A-10 championship game last season in its first attempt.
