The Charlotte Observer has an article up discussing Coach K's Olympic role and why it has nothing to do with Duke's recent "modest slide." They correctly point to recruiting, but what they don't discuss is just how much recruiting has changed. It's not just UNC doing a better job in that department. It's systemic.
So to continue the theme, we don't know what they're basing it on, but SI is quoting the St. Paul Pioneer Press as saying that Harrison Barnes will choose between Duke and UNC.
