Brown admitted the things he did and given his instability, there's no reason to doubt him or her. I don't believe I have read anything about money, I could be wrong. She left and he kept calling her back to help him train, after the incidents they both described, she wanted nothing to do with him.

She tried to get AB to invest $1.6 million in a business idea right after he signed a contract with Pittsburgh, and became angry when he refused. No one has corroborated her story. He is a hood rat, no doubt, but so are hundreds of other players who have lower profiles so we (thankfully) never hear from them
