well, before you do something, you need to think carefully about what will be the effect on yourself and most of all on the majority? Imagine, you are part of a team, but you are going to disclose information that someone can use to make money, that seems unfair to other bettors who have no idea at all while they trusting your ability, right? if he is banned from the NBA, I think that's right, he deserves it because he has no respect for the game rules, what he did when he disclosed about his health condition, seems like it was intentional for the sake of gambling winning and maybe he is also one of the Gambling participants that's why he could have done that incident.
