If you've got an hour and want to understand the origins of all the Manly hate and Manly jealousy, then this video is essential viewing.
It's an account put together by a Wests fan of the '78 season, with extensive player/coach/administrator/referee interviews. And shows how Roy Masters, quite deliberately and strategically, artificially manufactured a frenzy of hatred in players, and then in fans, creating the illusion of an us v them class war. It shows how gullible and easily led people can be. Masters, himself, didn't live in a fibro house, as that was quite below him.
