But a much easier argument against sports betting is that it ruins the sports. Players throw. They get good at subtly cheating. The gambling apparatus latches itself to the sport, to the teams and players, the umpires and judges, the sporting organizations. With this much money on the line, it's not a matter of if but when games are thrown, cheated -- the bigger the game, the bigger the incentive. It's even easier now because of the amount of side/parlay betting that is available. It exhausts the spirit of competition.
Sports gambling is diametrically opposed to sport itself.
Last week in the NFL there was a player that went down at the one yard line and his team ran off the rest of the clock to win. The game was under the O/U but would have been over if the player had gone into the end zone. The player made the choice so that his team could run out the clock without giving the ball back to the other team, and if he had scored then they would have had to kick the ball back to the other team who could potentially (although unlikely) scored a touchdown on the kickoff or in the last few seconds after the kickoff which would have given the other team the game. It was, objectively, the right thing to do in the circumstance.
The NFL analysts (who shill gambling apps) spent more time talking about if the player was responsible for everyone who lost on the O/U, and it just really killed it for me. Every. Single. Aspect is filtered through the lens of gambling. Games show the betting line on the screen and the analysts try to map out potential good parlays for the viewers. It's absolutely nuts and a very (in my mind) clear conflict of interest. It also blurs the line, in my mind, between objective reporting, analysis based on statistics, and paid promotion, and while I realize that sports reporting is probably the least important field in journalism, it's frustrating to see this unholy confluence and to see the impact it has on the ability for non-degenerate gamblers to enjoy the game.
