Report: Joe Dumars was fined $500,000 for leaking NBA memos

In 2010, the NBA fined former Pistons president Joe Dumars $500,000 for leaking multiple confidential league memos to Yahoo! Sports' Adrian Wojnarowski, according to multiple sources.

This matches the third largest publicly known fine the league has ever handed down. The NBA decided that too many memos were making it into the media, so they conducted a sting operation over several months and caught Dumars red-handed, as well as an executive from another team who was fined $12,500 for leaking to a draft-focused website

Joe Dumars, the Detroit Pistons, and the NBA all declined to comment on the fine.
