Is this the demise of the Phoenix Suns?

The Suns are now 2-4 with Shaq, including 1-3 vs. .500 teams. Phoenix fans keep saying they'll click soon and will be a championship soon. It doesn't seem that way. Realistically, how long until they can gel? They are winning only 1 out of every 3 games against west playoff teams. Shaq and Amare do not always get back on defense. Nash is turnover prone. Shaq tries to do moves like when he was in his prime. With their tough schedule, do you see them dropping to 6-8 or out? Is their window shut?
