Emm ... hmm .. let's see
There is Chris Paul and Deron Williams. LeBron, Wade, Roy and Durant. Possibly Evan Turner too. Chris Bosh and Dwight Howard. Maybe Oden or Bynum. Possibly Blake Griffin. Maybe Carmelo but he is right on the edge. Not sure about Tyreke Evans but he play himself onto this list over the next 12 months too.
Somewhere around 10 players. Needs to be an All-NBA level talent + be young, preferably under the age of 26, enough to build around long term.
I would also consider a package based around Steph Curry + Anthony Randolph.
