Flawed statement.
If Jabari, Randle, Smart, or Exum were taken ahead of him and they turned out to be all stars and Wiggins turned out to be a superstar (A Tier higher), you still keep your job. Its the equivalent of the Cavs taking Wade or Anthony over LeBron. Wrong choice but they still land a great player. You don't lose your job for drafting a multi year All-Star, even if you pass on Michael Jordan or King James. Draft is a crapshoot. Nothing is certain,
