Say Grisham does write this book, it sells millions, gets made into a movie, then makes millions more. Then he cuts us a fat check from the proceeds. Also, while filming the scenes in Starkville, all the actors fall in love with it, move to town, cut fat checks to expand the stadium and build some new luxury suites, they all get condos in town, and the town reaches new levels of swankness. Then somewhere along the line, Gameday comes to Starkville because that's all we ever really wanted.
This is obviously a long con by the the Ninja.
