Duke KyrieDuke is just three days away from beginning its national title defense. The Blue Devils open up Friday night against Siena, but there are over a dozen former players currently in action in the NBA.Like other programs with a large number of NBA alumni, Duke does a good job of playing up its track record on social media. It did so again tonight with a quick “Duke in the NBA” graphic on Twitter. Pretty self-explanatory. There’s background music, as images of ex-Dukies in NBA gear appear and flow from one to the next. Duke forever. #DukeintheNBA #BannerHunters #TheBrotherhood #DukeFam pic.twitter.com/3DnvM2cVcF— Duke Basketball (@dukeblueplanet) November 11, 2015How many members of the 2015-16 Blue Devils will join these guys in the professional ranks next year?
