I don't think it's correct to say that the book "The Blind Side" was a "biographical novel." Though the Wikipedia page about the book points out that it contains two storylines, one about the history of American football tactics and one focusing on the life of the player Michael Oher, there is no indication that the story of Oher's life was fictionalized in the book, which would make it just a "biography" and NOT a "novel."
