I mean, it's something that everyone has known about Floyd forever. But is it really on boxing writers to discuss stuff outside the ring like that? It's not a sport like baseball/basketball/football where you're so into the lives of players for consecutive months at a time that you can't help but write about personal things. Boxing is you cover the guy when a fight is announced, address his status periodically during camp, cover him the week leading up to the fight, cover the weigh-in/fight/post fight and then write your report. You'll only see them really address personal issues when something breaks or if it's really slow times in boxing.
There was a boxer a few years back named Edwin Valero who used to always be in problems for abusing his wife. This was a guy who was knocking out every one set in front of him and had a big following. You never heard about his personal demons after the initial story. Even when he killed his wife and then killed himself, I saw articles for a few days maybe and then it was right back to the world of boxing as normal. Whether it's right or wrong, it's how it is IMO.
