Could Exum or Randle crack the top 3?

So much has been written and said about Jabari Parker, Andrew Wiggins and Joel Embiid over the last few months, it seems like a foregone conclusion that they'll be the first three players selected in next month's NBA draft.

But as the Cleveland Cavaliers showed last year when they shocked the world and selected Anthony Bennett No. 1 overall, nobody knows for sure until the names are called.

With that being said, could other highly rated players, such as Kentucky power forward Julius Randle or Australian point guard Dante Exum, vault ahead of Parker, Wiggins or Embiid, and crack the Top 3? I reached out to ESPN Insider Jeff Goodman to find out if either might have a chance.
