From what I remember in Brian Orser's memoir, there wasn't much of a rivalry until Boitano came out of nowhere to win the 1986 Worlds. After that I can't remember. Has Boitano done a book?
Speaking of Orser, does anyone know what he's like? I felt a little put off after reading his bio by the tone of some of his comments but I know things can sound stronger in print. I'd like to still think he's a nice person.
