As long as Sacramento continues to lose and miss the playoffs, Cousins is and will not be far off the trading block. Good likelihood Cousins demands a trade sometime in the next 12-24 months given how bad a job the Kings are doing of putting talent around him.
Yes, sure, but what leverage does he have given that he's recently signed a long-term extension? Why not just try to turn things around and wait him out, if you're the Kings?
That is acceptable - for now.
Another year? two years? Will it still be acceptable to Cousins? Missing the playoffs.
That will be 6-7 years in the NBA without even getting to the playoffs for Cousins. How patient is Cousins going to be? How many superstars do you see go their first 7 years in the NBA without making the playoffs + stay loyal to organization ... to believe in their capacity to build a winner around that star?
This is still very much in play. Not right now but in the near future. Next 12-24 months.
Sacramento has an awful lot of work to do to get the Kings back into the playoffs in an incredibly tough Western Conference. Especially given the lack of talent around Cousins on the roster already.
