Since 2000, the #1 pick has been an All Star 74% of the time. The only busts were Brown, Barngani and Bennet. And Embiid's name doesnt start with a "B", so we're good.
Seriously, I don't think anyone would trade Deron in his prime for Wiggins or Embiid.
So, we'd have to give up a lot to get to #1, but it would be worth it.
