Major shakeup in West ... after the Spurs, that is

For the past five years, the Western Conference teams have dominated the East.

This looks like the year the pendulum starts swinging the other way. Only two teams in the West, the Kings and Rockets, significantly upgraded while several playoff teams -- the Mavs, Grizzlies and Suns -- were significantly weakened this summer.

That leaves room for cellar dwellers such as the Warriors to finally break through, while the dream may be over for former Cinderellas such as the Grizzlies.

Insider breaks down how this summer's moves will likely reshuffle the standings in the West next season.
