Consensus all-American Cooper Flagg, the ACC player of the year, sprained his left ankle in the ACC Tournament and missed Duke’s last two games. The Blue Devils play Mount St. Mary’s on Friday.

Duke’s current efficiency is 38.15, the nation’s highest since the 2001 Blue Devils ended the season, with an NCAA championship, at 37.32. The only team with a higher KenPom efficiency at time of the year? Duke’s 1999 team that went 37-2 and finished with a 43.01 efficiency.

Duke basketball is heading into the NCAA Tournament with as much confidence as any team in the country. The Blue Devils are coming off a dominant ACC Tournament victory after running through the conference during the regular season.
