Huggs probably was drunk. It's no secret the guy abuses/abused alcohol. He did it in public and we have learned (more than once) he did it in private. The guy has probably been in a dark place for a long time. Just as he and the University of Cincinnati expressed he was back in 2005 - and probably was long before that.
Problem for him is/was what I alluded to yesterday. He had many enablers and while a few people may have wanted him to seek the help he MAY have needed, it was HIS choice and he preferred to not get help. He's somewhat paying the price for it now. Thankfully for him he can and hopefully will still live a decent rest of his life.
