Parker is and has been my choice. Fills an actual need on the team too. embid is just an upgrade, but w/ Kanter, Favors, and Gobert: we aren't hurting at the center position, and Parker is still BPA IMHO.
For me it is:
1. Parker
2A. Wiggins
2B. Embiid
I would also be happy with Exum or Randle. The more players that challenge for the top three when you have Parker and Wiggins in the draft is that much better for Utah. Increases their chances of landing that franchise player.
Edit: When and why did Randle start falling out of favor on here?
