DeMarcus Cousins has said he won’t demand a trade out of Sacramento, but that might not stop the Kings from moving him to install a veteran presence in their young locker room. According to ESPN.com, if/when Sacto does decide to test the trade waters, the Boston Celtics and Detroit Pistons are willing to talk business: “The early word from the DeMarcus Cousins trade watch, according to the latest rumbles on the personnel grapevine, is that Kings co-owners Gavin and Joe Maloof remain reluctant in the extreme to part with their young big man, especially at a time when — after three suspensions already this season — Cousins’ trade value isn’t exactly on the upswing. There’s a growing sense among potential suitors that under-fire Kings general manager Geoff Petrie, who has overseen zero trips to the playoffs under five coaches in the six-plus seasons since Rick Adelman left town, would be willing to move Cousins, preferably in exchange for a dependable veteran of quality or two who could bring some instant improvement to a franchise stuck in lottery land and still plagued by an uncertain future in terms of where this team will be calling home in the long term. [...] Front-office sources say that Boston and Detroit, just to name two teams, have let it be known that they are highly interested if and when Cousins does become available. Rest assured there will be more.”
