Duke has had two men's basketball teams this season.
There was the Duke team that swept the Maui Invitational, stumbled against Pittsburgh, won at North Carolina and was the nation's most impressive club for a long stretch of the regular season.
And then there was the other Duke, the team that appeared during the middle of February. It has had little resemblance to the earlier version.
Those are the Blue Devils who dropped successive road games at Wake Forest and Miami, struggled at N.C. State, lost at home to Carolina, then looked tired and hesitant during last week's ACC Tournament in Charlotte.
