It is still more likely, sources familiar with the situation say, that the Sixers complete a deal for Harden or a player of Harden’s caliber in the summer, rather than in the next six days. But the Sixers are, as they have been for months now, prepared to move quickly if they feel the right opportunity is on the table. As we reported earlier Friday, no player on the roster (save for Joel Embiid) is untouchable in trade talks, depending on the player(s) on offer. And the team has insisted for a while now that this is not a Harden-or-bust push, a claim they feel has been made for dubious reasons elsewhere.
