I don't really care if it's drugs or alcohol or something else. Unfortunately, he's lived a troubled life. It's not like we need to either try to hurt or help his reputation at this point. It is what it is. Why bother with this stuff anymore? Either you dislike him because of his troubled past or you accept he's a troubled person but you were a fan of his athletic accomplishments.
Hopefully it's not life threatening and he can recover. Doesn't sound to be life threatening, which would be good news.
At this point, I don't think you can really have any expectations with his pro career anymore. Even if he wanted to come back, he's 45 years old and best case scenario probably has two broken legs. Thats likely at least all of 2021 he misses. So if he comes back at age 46 off of two broken legs, what can you really expect? He already has significant back problems, he'll be trying to recover from two broken legs, and then there's the fact that he's pretty old for a professional athlete with many surgeries and injuries. It's hard to think his body could hold up to professional sports anymore.
