I'm fully of the belief that I don't think Cousins is actually on the market right now, and they'll at least attempt to see what the team will look like this year with Joerger at the wheel.
However, does Sacramento stand any chance whatsoever at making the playoffs in the West? If we break them down by tier, I don't think there's much more than an outside shot:
Guaranteed to be in the Playoffs - Golden State, San Antonio, Los Angeles Clippers
Probable to be in the Playoffs - Portland, Dallas, Memphis, Houston, Utah, OKC (w/Westbrook)
Hopeful to be in the Playoffs - OKC (w/out Westbrook), New Orleans, Minnesota, Denver, Sacramento
Doubtful to be in the Playoffs - Los Angeles Lakers, Phoenix
So I think any potential trade for Cousins will come closer to the deadline when the playoff picture is better set. I firmly believe that barring any big trades or injuries, there are at least nine teams, including OKC w/Westbrook, that are clearly better than Sacramento. Hopefully, the combination of them being outside the playoff race and the Nets looking horrible again will finally encourage them enough to trade Cousins at the trade deadline. I think those are two things that will almost necessarily have to happen to end up forcing them to trade him to us.
