Andrew Greif: The Clippers pride themselves on operating in silence — one league source once said it has been described within their building as “ninjas in the night” — so speculation can often lead to dead ends. Yet there is an expectation around the league that their three-center rotation, which has not truly worked all that well for anyone involved, will be resolved with a center expected to be gone. Serge Ibaka’s the most likely candidate because of his expiring salary, but there are scenarios, team president Lawrence Frank has said, where he returns. Some around the league take that to mean that there are scenarios where potentially Ivica Zubac could be packaged and sent elsewhere as part of a bigger move.
