Eli5: Why are professional athletes typically banned from placing bets that are in favor of their own team/themselves?

Question

I understand why you would not want athletes to throw games on purpose if they place a large bet for the opposing team to win, however let’s say I am a pitcher in baseball, and I place a bet for my own team to win, wouldn’t that only motivate me to play better because I stand to win more money by doing so?

Answer 1

Let’s use Pete Rose as an example. As a mgr, betting on your own team to win means you are willing to make managerial decisions to win your bet. Even though those decisions are a detriment to your team, like bringing in a reliever when they may need more rest.
