NCAA: An inside look

Day 4 heroes

Stephen Curry, Davidson: Curry scored 55 points in the 10th-seeded Wildcats' pair of NCAA upsets -- and that's if you're only counting his second halves in those games. Curry drilled Georgetown for 25 points in the final 15 minutes to lift his team from a 15-point deficit to a 74-70 victory.

Courtney Lee, Western Kentucky: The future NBA shooting guard led the 12th-seeded Hilltoppers to their first Sweet Sixteen since 1993 with 29 points and 7 rebounds against San Diego.

Ben and Tyler Hansbrough: Mississippi State's Ben scored 19 points, 1 off his season high, as he and teammate Jamont Gordon nearly rallied MSU over Memphis. Tyler had 19 points and 10 boards as UNC rolled Arkansas.

Day 4 zeros

Roy Hibbert, Georgetown: Blessed with a huge size advantage against Davidson's front line, the 7-foot-2 senior fouled out in just 16 minutes. He took just 3 shots and finished with 6 points.

Mike Green, Butler: If the Horizon League's player of the year has a normal shooting day, the Bulldogs stun Tennessee. Instead, Green went 4-for-17 from the field, 6-for-10 from the line and committed 6 turnovers as the Vols escaped in OT.

Memphis' shooting eyes: Are the top-seeded Tigers trying to bow out early? Memphis made 5 of 10 free throws in the final 33 seconds as Mississippi State went from 8 points down to a 75-72 loss -- and the Bulldogs rimmed a 3-pointer at the buzzer.
