Problem is bad calls and missed calls go both ways. But some people have blinders on depending on whichever team/player they dislike so only when a call favors that team do they notice it.
Otherwise the missed calls are ignored.
Example last night people made a fuss about Lebron stripping Hill and how it was a foul. When I thought it was clean but even if it was a foul and missed, on that same play when Lebron was going up for a layup PG clearly hacks him across his wrist and its also missed. No outrage there.
Selective ref whining is just annoying. NBA refs overall aren't great and yes superstars get calls but it goes both ways and both teams by the end of the game get some calls in their favor.
