Duke was 22-1 on Feb. 13, and looked like one of the strongest teams in the country.

But over the final stretch of the season, the Blue Devils were bounced in the ACC Tournament semifinals by Clemson and in the second round of the NCAA field by West Virginia. In fact, Duke barely survived Belmont in the first NCAA game.

So what happened? A look at the Blue Devils' statistics reveals some of the problems.

After Duke beat Maryland on Feb. 13, it was averaging 85.7 points per game and shooting 39.3 percent from three-point range.

In the next 11 games,  Duke suffered five losses. In those games, the Devils averaged 78.2 points and shot 34.7 percent from three-point range.

Duke had more turnovers (156) than assists (143) in its final 11 games.

It also suffered through scoring slumps from senior star DeMarcus Nelson and freshman Kyle Singler. Nelson averaged just 12.8 points and Singler 11.1 over the final 11 games. Nelson was averaging 15.3 points and Singler 14.3 on Feb. 13.

Finally, the Blue Devils ran into teams that were physically tougher and stronger, as the rebounding totals suggest. Duke was out-rebounded 38.2 to 36.3 rebounds per game over the final 11 games.
