The players OKC has cast off would be the core of a championship team: Durant, Dipo, Harden.
Yeah, just going back to the 11/12 Finals team, the following players have played for and are now no longer on the Thunder
PG - James Harden, Reggie Jackson, DJ Augustin, Ish Smith
SG - Victor Oladipo, Dion Waiters, Jeremy Lamb
SF - Kevin Durant, Doug McDermott, Thabo Sefolosha
PF - Serge Ibaka, Taj Gibson, Lance Thomas
C - Enes Kanter, Ersan Ilyasova
That is the best team in basketball. Not sure any franchise could even come close to that level of talent in the same timeframe.
