Duke and Mike Krzyzewski usually get more than their share of free positive media coverage. Both the university and hall of fame coach likely welcomed a change of media focus Tuesday after a day of coverage surrounding details in an upcoming book by Ian O’Connor that reportedly details more about the school’s choice of Tommy Amaker to lead the basketball program and the coach’s preference for eventual coach-in-waiting Jon Scheyer. Mark Williams granted that wish with a game winning put back against Wake Forest when Paolo Banchero’s shot rolled off of the front of the rim with .4 seconds remaining in the game. Duke showed some vulnerability by giving up a 19-point second half lead with Krzyzewski out sick after halftime, but the Blue Devils will surely take the win and 1/2 game lead over Notre Dame for first place in the conference.
