There is a STRONG rumor that Westbrook will be traded to the C's for players and those Nets draft picks the C's control.
Certainly makes sense for OKC. Assuming he doesn't bolt Boston ...makes sense all around.
Could be risky for Boston though. Next years draft class is supposedly loaded, and the Nets could very well be the worst team in the NBA next year by a good margin, and I doubt they'll improve much in a few years either. Westbrook is great, but there's risk there because he could be a 1 year rental if he bolts for free agency the following year. They'd be rolling the dice that he could learn to love playing in Boston and they could entice him to stay by obtaining his Bird rights.
I've heard the C's linked to Blake Griffin and Demarcus Cousins as well. Gordon Hayward's name has also been thrown around. It wouldn't shock me at all if he joins them once he hits free agency to reunite with Brad Stevens, if not sooner.
