Bones, what's the currency in the NBA today?
I would submit that it is the following, in order of being coveted (by most rational GMs...some variance based on team situation, but in general...):
1) Transcendent players (Durant/Lebron)
2) All-Stars under 27 on non-max contracts (roster flexibility for a potential Big Three...think Steph Curry, Dame)
3) Future unprotected 1sts (lotto possibilities)
4) Good players on rookie contracts
5) Future "Jermaine O'Neals" on cheap contracts with upside
6) Future Protected 1sts
7) Good players coming off rookie contracts that you must overpay to get away from RFA
8) Cap Space (because it can generally get you #4, #5, #6 or #7 above)
9) Former All-Stars on max contracts
10) Role players on good contracts (Redick, Korver...)
...
37) Expiring contracts
...
194) Joe Johnson
...
Hell) K*be
You'd be trading a #5 for something that's not even top 10 (role player on non-good contracts)
