In every sport worldwide there are teams that have some league help. And every fucking time these teams are good teams that many people want to watch them more. That's how it works.
I am not saying that the refs will make a bad team win a series but they won't make them lose the series. For example if the Bulls* trail by 10 in the 4th they will give them all the calls that they deserve. They won't let one single call. It will be fair calls. Good calls. But if they were not the Bulls and the other team weren't the 6ers some of the calls may not been given. If the Bulls don't manage to win it then bye. And that's fair for me because it's business. You want good and/or popular teams like Chicago,Celtics,Heat,Knicks,Lakers to be in the TV as far as possible.
*instead of Bulls you can put Heat,Celtics,Lakers,Knicks or whatever good big market team you want.
