The salary issues will catch up with GS, don't worry. As for the East, what do you expect? LeBron is a badass and other than that the Cavs aren't unfairly stacked like the dubs.
There will always be ring chasers that play for less for a chance to win a ring. Nothing they can or should do about that.
I mean, for all the crying people did about Lebron, Wade and Bosh taking less money to team up, those same people turn around and praise Spurs players for doing essentially the same thing.
The league doesn't have an issue to address, other than insisting next time around that a big cap jump be spread out. Had they done that this time around, they would have probably had a lockout and then people would be complaining about that instead. The Warriors have a good chance to win several championships, but things will level out at some point.
I have a feeling GS can, and will, keep paying luxury tax as long as they keep winning. They're building a freaking stadium out of their very own pocket for crying out loud.
