In the Sept. 5 meeting, Cronin conveyed that if he was forced to do a deal with Miami, he had every intention of going after every attractable asset. Lillard knew then he was unlikely to end up in Miami.
Lillard then said if a deal couldn't be worked out with the Heat, he would prefer to rescind his trade request and return to the Trail Blazers.
Cronin's response to the seven-time All-Star was that there was no coming back.
Lillard was shocked, sources said. He said it was discouraging to hear he couldn't return, but added that he didn't want to be somewhere he wasn't wanted, and he ended the meeting.
Lillard was still hopeful a deal with the Heat was within reach. However, he had to face the realization that he might not be moved.
