One big difference is with a NBA team there are only about 9 - 11 other primary contributors, maybe some coaches and back office staff. At any large company there are tens of thousands pulling the boat (pick your metaphor), however the rest have limited bargaining power (without a union). CEOs sit on the board and are good friends with board members and often return the favor on other boards and networks.

CEO wage negotiations have nothing in common with employee wage setting.
