I'm not concerned at all.
OKC is not going anywhere. Spurs are not going anywhere. Denver with Iggy is a very good team. And I can make the case, that if Bogut and Steph is healthy, the Warriors, with how deep they are, can give anyone in the West a run for their money.
Not worried at all one bit. I'm more worried about Philly, Bynum is primed for maybe a monster year now that he's "the man". And Philly has studs in that lineup as well.
