I hate seeing posts, articles and comments after every questionable game or call by a referee. It's such a lame excuse.

1. It is nearly impossible for any outside influence to impact how the players perform enough to control the game's result. It's preposterous for people to think players are so good or even aware of those external factors and can just change the game on command. Sports are hard and no players are involved in changing outcomes.
2. If by rigged you mean one or two things happen throughout a game (officiating-wise) and it looks fishy betting-wise... who cares! Sports aren't about betting. If you lose a bet because some player does something that looks like it was intentional because it went against Vegas' omnipotence, that's on the viewer not the league or game. If anything, knowing there are people that can lose money on stupid stuff like that, it's even more entertaining.

People assume way too much from sports leagues to be able to pull off the rigging they assume is happening.
