I'd prefer the better player in Cousins, but just maybe you can hold onto the Nets picks trading for Griffin in the last year of his contract.
I think the Kings are stupid if they think at this point they can hold onto Cousins long term, and his value will only go down the closer he gets to FA.
Maybe trade for Griffin now, re-sign him next offseason if all things go well, then trade for Cousins. Horford then off the bench in a Bill Walton role. Ha I'm kidding, but that would be awesome.
