Former NFL player Michael Oher claimed that he was never legally adopted

According to public statements, they didn't raise him. He says he occasionally stayed with them during his junior year and was invited to move in with them prior to the start of his senior year. That would have been a short amount of time between living with them and signing the conservatorship. They may have shown him kindness but he knows best if he thinks, based on what he says he learned in February of this year, that was to take advantage of him.
Terrible if they took advantage of a child in need. That's one of the lowest acts a person can do
