Georgia football great Herschel Walker has multiple personalities -- a revelation in an upcoming book that surprises the man who coached the 1982 Heisman Trophy winner. "That's all news to me," former Georgia Coach Vince Dooley said in Friday editions of The Atlanta Journal-Constitution. "All I know is whatever personality he had when he had the football was the one I liked." "Breaking Free" will chronicle Walker's life with multiple personality disorder, according to Shida Carr, a publicist at Simon & Schuster.
