GREENVILLE, S.C. (AP) No. 2 seed Duke (29-7) vs. No. 7 seed South Carolina (23-10)
Second round, East region; Greenville, S.C.; 8:40 p.m. EDT
BOTTOM LINE: Count on tight defense from both teams. South Carolina plays a disruptive designed to take opponents out of their comfort zones. The Gamecocks are 27th nationally in points allowed this year. Duke is 21st in the country in scoring margin.
THAT'S SWEET: Duke is looking for its record 24th trip to the round of 16 under coach Mike Krzyzewski. He's won a record 91 tournament games.
WHERE'S LUKE?: Blue Devils leading scorer Luke Kennard was held to eight points in Duke's 87-65 win over Troy, the first time in 19 games he was not in double figures.
LOOKS FAMILIAR: South Carolina coach Frank Martin said he learned his defensive principles from his fascination with then high school star Tommy Amaker, who played his college ball at Duke. When Martin's high school team lost to Amaker's W.T. Woodson High in a holiday tournament, the Gamecocks coach pledged to follow Amaker's career. That led to Duke and coach Mike Krzyzewski. ''Between my high school coach and watching Duke defend is how I've kind of developed my philosophies,'' Martin said.
DID YOU KNOW? South Carolina last won two NCAA games in the same tournament in 1973. Duke accomplished that last year.
