From his formative years in western Pennsylvania to working his big brother's staff, Archie Miller has spent most his life in Sean's shadow.

Well, look where Archie and the Dayton Flyers are now: In the Sweet 16, just like Sean and the Arizona Wildcats.

They have become the first brothers to coach separate teams in the NCAA tournament's regional semifinals at the same time.

Arizona, the No. 1 seed in the West, is in the Sweet 16 for the third time under Sean.

Dayton has become the mid-major darling of this year's tournament, reaching the Sweet 16 for the first time in 30 years after surprising wins over Ohio State and Syracuse.

Dayton plays Stanford Thursday in Memphis. Arizona plays a couple hours later in Anaheim, Calif., against San Diego State.
