I'd love to see them get a legit center that can rebound and block shots.
It would have been great if they nabbed DeAndre Jordan last summer but that didn't work out.
My number 1 option would be to get Embiid.
Option 2, if they don't get Embiid would be to make space to offer Gortat around 9-11 million a year. He's helped Washington get to the playoffs and would be a perfect anchor to the defense. He's an offensive threat and is young enough to be part of the core for the next 5 years.
Option 3 - if they get in the top 3 but get Jabari Parker, try to trade him for Andre Drummond, LaMarcus Aldridge, Big Al or Demarcus Cousins. To get Aldridge or Al you'ld have to throw in some more assets or contracts to make the money match. Same with Kevin Love(not a center but it's Kevin Love)
