What nine players do you really need if your big four is Durant, Harden, Ibaka, Westbrook?
13 mill is fine. Buy 3 2nd rounders, draft your late 1st. You've got 10 mill for 5. Take the best summer league standout and 4 cheap fisher-like vets.
But I actually love the harden deal. I don't know how everybody says okc isn't deep. Outside they're big 3... Jackson, Adams, Lamb, Jones, Roberson all have potential. Then Butler, Perkins, Fisher, Sefalosha, Collison are all Bonner+ level role players.
They're problem is Brooks and mental toughness.
