Brisbane sport followers bandwagon jump when teams are flying well. Look at the crowds at Reds and Roar games recently.
When the Lions had their success on field, they had a higher average attendance than the Broncos 6 years in a row (2000, 2001, 2002, 2003, 2004, 2005). You either have to admit that bandwagon support jumped on the Lions during their successful period, or that for
6 years, Australian Football was more popular than Rugby League in Brisbane.
Personally, I choose to believe that the Brisbane sporting public jumps on a winner, and jumps off when the winning stops.
