Featured Matchup: Duke vs TCU

The Duke Blue Devils enter the second round as the No. 1 seed in the East Region, though they are coming off a narrow six-point victory over Siena where they trailed at halftime.

 All eyes are on freshman phenom Cameron Boozer, who remains the focal point of the offense, but Duke will need more consistent play from its backcourt to handle the pressure. 

They face a TCU Horned Frogs team that dominated Ohio State in the first round and brings a top-30 defense into this Saturday showdown, looking to reach the Sweet 16 for the first time since 1968.
