I hate to think games are fixed, but why do people find it hard to believe?
Corruption is found in every single industry, so why would sports and gambling, which go hand in hand be exempt.
Drugs have proven to a problem in sports, Steroids, Weed.
We have seen refs, players involved in point shaving/fixing. The NBA is a for profit organization who has created rules to make the game more entertaining, in order to garner higher ratings and greater ad revenue.
Why do you think teams are allowed to advance the ball from their own basket to the other 3 point line.
