What the Houston Rockets decide to do at No. 4 in the draft could tip their hand on whether they expect to sign James Harden in free agency.

While Harden is expected to choose between the Rockets and Philadelphia 76ers, the momentum for him to return to Houston appears to be slowing down.

ESPN's Jeremy Woo writes that Harden signing with the Rockets has become "a situation that rival teams have come to view as increasingly uncertain in recent weeks."

Harden has recently been described as "torn" between the two franchises. The Sixers parted ways with Doc Rivers and hired Nick Nurse as his replacement as head coach.
