Cousins. Heres why:
Love isnt good enough
Jimmy isnt on the block so getting him would mean overpaying which would mean Brooklyn + Smart + probably Crowder just to get a conversation going. (wouldnt be surprised if we had to throw in Bradley). When a star isnt on the block they are virtually unatainable.
Blake: I also am not sure if hell wind up on the block and I overall just dont like him. That being said If he could be had for Brk + Smart Id certainly do it.
Cousins: With all the issues it looks like this summer he could finally hit the block in earnest. Hes a huge risk because of the personality stuff, but the bright side is hes a way bigger risk for teams that dont have solid cultures in place (LA, Philly, NYK). For those teams (the teams with the assets we cant match (Porzingis, Russell, top 2 picks, Okafor, Noel) ) Cousins is exponentiallly more risky than for us. All these factors combine to the point where I think Demarcus could be had for Smart + Brk '16. His talent level for that price is absurd.
He also has the lowest salary cap hit of the group next season, so we will be able to put a stronger team around him and KD if we get him.
Thomas-Cousins-KD is a nice big 3 and the supporting cast could still be stellar as I think we would be able to keep AB, Crowder, Turner, Sully if we wanted to, and KO
