I brought up the idea of "The Curse of Norm" a while back (I think it was under a different username) and I was laughed at by many on this board.
The fact is, what Norm created at the MFC was a culture that was probably the best in the league at the time and probably the most prestigious and powerful in the history of the game. With Norm's sacking come a complete turn around and a different culture; a culture that has lingered at the club for 42 years.
The way I look at it? Coaching from 52-67 (16 seasons) for 6 premierships including a triple (55,56,57). That's one premiership every 2.5 years. Since then? 40 seasons. 0 premierships.
I've always believe that his tenture at the club was what made it so successful, both playing and coaching. Obviously his style was not attractive to his collegues, hence why he was forced out. However, that style and voice was part of 10 premierships over 32 years. He leaves, and the streak begins. We need another Norm.
