One of the newspaper articles stated he is bipolar and was off his meds in relation to this assault indictment.
Manziel was the same and he was a party animal who also assaulted his girl friend.
Then there the sad story of former Frog, Barret Robbins, whose erratic behavior leading up to Super Bowl XXXVII revealed his battle with his bipolar disorder on top of his recreational as well as performance enhancing drugs use causing him to disappear the day before the big game, not to mention numerous assault & battery charges in the succeeding years. He's spent over a decade in and out of jail & rehab only to end up in a mental health institution for assaulting a mother & her child in '16.
It's no joke, and I sincerely pity him and all those unable to have the right support system around them as they grow into young adults and beyond, especially when surrounded by their 'posse from the hood', and the glamorous life of being a gifted athlete (singers, actors & etc.), that energizes a disconnect from reality.
