I've been running this scenario through my head for a while:
Let's say we've got a college game which is truly a PICK, both teams have a 50% chance.
Some rich person manages to bet $100,000 on one of the teams through several books.
This rich person goes to the team he bet on and offers say the top 7 players $10,000 each only if they win the game.
Thus, the rich person would pocket about a $20,000 profit if they win. In a truly 50/50 match the extra motivation of the payoff could turn it into 70/30 odds at least imho.
How in the world would this type of "fixing" be illegal? In essence, the rich person is offering a GIFT if a certain thing happens. People are allowed to give gifts for any reason in most cases. Would this be illegal?
