Duke's back-to-back national title hopes were dashed by the University of Arizona in the Sweet 16 back on March 24th, 2011. The Blue Devils were unable to match Derrick Williams' athleticism as the Wildcats ran away in a 93-77 dunkfest.
The loss spelled the end of an era for the Dukies, as Coach Mike Krzyzewski lost his two senior leaders in guard Nolan Smith and forward Kyle Singler, along with projected number-one draft pick Kyrie Irving. With Smith and Singler gone, only the Plumlee brothers (Miles and Mason) remain as regular contributors from the 2010 National Champion squad.
Duke is expected to be a top-10 team every year; Coach K always seems to put together a solid, if not elite, squad. Given the team's pedigree, anything short of a national championship is considered a failure. Here's why they won't win it this year, and some reason why they're in trouble in the years to come.
