A hard-fought 72-65 home win over the Louisville Cardinals on Monday marked the first time during the 2015-16 season that the Duke Blue Devils knocked off a ranked opponent. It's been that kind of year for the Blue Devils, who are defending national champions but are nothing like the team that won it all 10 months ago in Indianapolis.
This season has been one of the most tumultuous in coach Mike Krzyzewski's tenure, but it's by no means a bad one. Duke has a month until the regular season ends and in that time has several big games to play.
