Russell Westbrook was focused on joining the Houston Rockets with other destinations "lightly considered," according to Royce Young of ESPN.
The Thunder were also in trade negotiations with the Heat, although the Heat balked at the Thunder's asking price for Westbrook.
Sources told Jonathan Feigen of the Houston Chronicle that the Rockets felt that a trade for Westbrook seemed almost impossible on Tuesday.
James Harden reportedly played a key role in getting Westbrook to the Rockets.
