Greensboro — The problems that bothered Duke throughout this basketball season surfaced in waves Friday night in Greensboro Coliseum against long-shot underdog Lehigh.

With Seth Curry missing eight of nine field-goal attempts and the Blue Devils firing blanks on 20 of 26 shots from behind the 3-point arc, No. 15 South Regional seed Lehigh left with a 75-70 win.

Duke, seeded 2nd in the South, never seemed to be comfortable and had no solution for Lehigh’s C.J. McCollum (30 points).

There was nothing left for the Devils (27-7) to ponder at night’s end except next season. Working on the assumption that freshman guard Austin Rivers will leave for the the NBA, Duke probably will enter the 2012-13 season with a group of reasonably reliable insider players and a perimeter that should include Quinn Cook, Tyler Thornton, Curry and Ryan Kelly, the 6-11 forward who sat out the game Friday with a foot injury.

The loss was the second of the opening weekend for No. 2 seeds, but probably rates as the most devastating in ACC history.
