The No. 3 Virginia Cavaliers will aim to play better defense in their rematch with No. 2 Duke on Saturday.

Virginia gave up a season-high 72 points to Duke in its first meeting with the Blue Devils three weeks ago in Durham.

Duke's Zion Williamson and RJ Barrett combined for 57 points, 79 percent of the Blue Devils scoring.

"First game we kind of lost our discipline and they exploited it as many good teams will do," says UVa's Braxton Key.  

Key scored 11 points for Virginia off the bench against Duke.

He is Virginia's leading rebounder and one of Virginia's best defensive players.

Key says the 'Hoos must do a better job stopping Zion Williamson in the paint, providing more help defense.

"You have to guard with all five players," says Key.  "He's not someone you can just go out there and go mano a mano.  Dribbles like a guard, jumps out of the gym, really athletic.   Moving forward I think we have good game plan coming up."

Virginia made just 3-of-17 three pointers in that first meeting with Duke in Durham and had chances to win but missed some open shots in the final minutes in the 72-70 win.

"We really can't count on them having such a cold shooting night," says Duke's Javin DeLaurier, who's from the Charlottesville area.  "They'll probably have more energy because they're tough to beat at home so it's going to be a different game.     But we're not going to play them exactly the same way and I'm sure they're thinking the same about us."
