Since 1990 only two coaches have won their first premiership after more than six seasons of trying at first-grade level – John Lang (Penrith, 2003) and Steve Folkes (Canterbury, 2004).
And only two coaches in that same 30-year timeframe have landed that breakthrough title after coaching 200 games – Lang again, and Manly Immortal Bob Fulton, who coached 229 games before winning the 1987 title, and 348 games en route to the 1996 premiership.
The average numbers of your premiership-winning coach – 99 games, four years into his head coaching career, and roughly 45 years old.
