Scott Teal is a great ghost writer for wrestling books. He sends you a packet of questions that you fill out and he does the rest. My dad was in the process when he died. Teal use to put out a monthly magazine called What Ever Happen To? About wrestlers.
It sounds like he does a good job.
Still, I prefer to read something written by the actual wrestler that is simply polished some by a copy editor. Foley's first book would have been QUITE different if assigned the ghostwriter the publisher had in mind.
