If they end up getting Philly's pick this summer, they would have that pick and their own pick in 2014, meaning they could trade one of them, right? Or is it that they can't trade one of those picks until they find out if they actually get Philly's 1st?
Edit: Philly's pick is lottery protected in 2013, 2014, and 2015, so since Miami doesn't know yet whether the Sixers will make the playoffs (transferring the pick to Miami), Miami can't trade its 2014 1st before draft night because it could leave them without a 1st in 2013 and 2014.
