While Zion Williamson‘s, R.J. Barrett‘s, and Cam Reddish‘s offense has dominated the highlight reels, it is the defense that has Duke winning games. A big part of that defense has been the Blue Devils’ ability to block shots and protect the rim. Duke leads all of Division 1 basketball in blocks per game with 7.2 and it has been a total team effort with four plays averaging at least a block per game.
