The officiating in the NBA can be pretty awful at times, and there's clearly different standards for stars vs non-stars. And the more subjective the call, the more inconsistent it tends to be. The league needs to take steps to remove the subjectivity, situational considerations, and especially the refs' egos from how calls are made.
But I don't think anyone here really believes it's fixed. If it was, why bother watching? If it's not, why say so? And again, if it's rigged, we're one of the biggest beneficiaries - we have 3 titles, 3 finals appearances, and several conference finals since Stern got here.
If you do believe it's fixed, I suggest a little test - judging things in hindsight is easy. But since the league is so blatantly rigged, it shouldn't be hard to make a few predictions in advance. Specific, clear ones that can be objectively true or false, not vague things like "LeBron will get all the calls, y'all".
Write em down and keep track of your hits and misses. The smart, discerning fans who see through this massive conspiracy should also be able to consistently predict how that conspiracy will play out, right? Those 3 straight years of Kobe-LeBron finals matchups can attest to that.
