Michael Porter, Marvin Bagley, DeAndre Ayton and Luka Doncic comprise the top-4 of the first mock draft from Jonathan Givony of ESPN for 2018.

Porter is a multi-talented, highly athletic combo forward.

Bagley reclassified to the incoming freshman class of 2017 and will attend Duke.

Doncic has been widely considered a potential top overall pick but scouts have concerns on whether he is athletic enough to defend his position as well as create his own shot.
