re: Oher blindsided, gaslit by Tuohy family; wishes he had gone to Tennessee

Per the article, he did know in 2011 and wrote about it.

Evidently, he has new representation (fyi... he had none other than the Tuohys when he was a senior in high school).
They are working to overturn the conservatorship.
I'm guessing that he expects a big sequel to the original movie.
