For Rajon Rondo, little has changed. He and those around him have long held that his intention for the final two years of his contract with Boston is to play out the deal, first showing that he is healthy after returning from ACL surgery last year, then bouncing back into All-Star form this year as he heads into 2015 free agency. Thus, sources on both sides disputed the suggestion that emerged this weekend that Rondo had requested a trade from the Celtics — it is still his intention to play out his contract in Boston, and it’s still the Celtics intention to begin the season with him as the starting point guard. That, of course, could change. Despite entertaining offers for Rondo for the better part of three years, the Celtics have not gotten an offer that worth pursuing significantly. If something did crop up that would bring in a young potential superstar, the Celtics would have to reconsider their stance against dealing Rondo — but with Rondo posting only so-so-numbers as he completed his rehab last year, his value is relatively low just now. Boston — and Rondo — could also change stances during the season. If the Celtics come out of the gate stumbling as a team, but Rondo shines as an individual, it would behoove team president Danny Ainge to look at mailing in the season, stockpiling more youth and draft picks and moving Rondo along.
