Rondo Yet sources told ESPN.com that talks between the teams have not progressed to a serious stage because the sides can't agree on a trade framework both can embrace.
One main stumbling block, sources said, is Boston's desire to acquire blossoming Houston swingman Chandler Parsons in a potential Rondo deal. But sources say the Rockets have informed the Celtics that they are not prepared to surrender Parsons as part of a Rondo package.
The Celtics have consistently denied that Rondo will be dealt before Thursday's 3 p.m. ET deadline. There have been strong indications all season that Celtics owner Wyc Grousbeck wants to keep Rondo in Boston to give the former All-Star point guard, who's still in the early stages of his recovery from a torn ACL, ample time to form a partnership with new coach Brad Stevens.
But the Rockets have made a trade at every deadline during general manager Daryl Morey's tenure running their front office and are known to covet Rondo deeply. Houston also possesses draft picks to deal and a cache of young players beyond Parsons -- such as disgruntled (and very available) big man Omer Asik, along with the likes of Patrick Beverley, Terrence Jones and Donatas Motiejunas -- to try to tempt the Celtics.
