Without Klay Thompson, the Warriors' ceiling is the 5 seed, but it could be much worse if their defense is as bad as I think it will be.
Portland was terrible at defending the wing after they traded Aminu and Harkless. The new roster additions will make them much more dangerous against the Lakers and Clippers.
Portalnd beat Denver in a Game 7 with Enes Kanter. The defensive upgrade with Nurkic, a healthy Collins and the new wings should give them a good chance to beat Denver in a playoff series should they meet.
