In defense of the "Market Value" issue:
It will be "Market Value" or off to court for Sterling and the NBA. He would be a fool not to go to court.
Equally probable is the sale at a premium to avoid a long and possibly losing court battle by the NBA. Certain bad publicity. Highly possible bad result. Is that worth the risk? I doubt it. The other owners will loan in the necessary money to get this over quickly. To me that means a premium for Sterling.
And what if he still doesn't want to sell?
