Whether it will be Hubert Davis or Wes Miller, their success will largely depend on when the 2005 and 2009 UNC titles will be vacated. If it happens enough soon(within 2-3 years), they will have less pressure and be given more time to take the program back to the level it was in 2016 and 2017. The pressure and expectation are very different, if the former coach won just 1 title in 15 years with UNC, rather than 3 titles. If it happens too late(ie. after 5 years), they may be running out of time as UNC wont be as patient with them.
Quinn Snyder is an excellent coach but I bet he aint taking the Duke job. The pressure is immense to succeed Coach K, one of the greatest coaches in NCAA history. Whoever will be Coach K's successor, he deserves full respect from everyone on this board whether he will succeed or not. I cant imagine myself handling such pressure when my predecessor was basically the entire history of a program.
