Why would you rebrand when we are in our most successful period ever? That doesnt make sense. The club has been built up into a fromidable brand thanks to the onfield success. You wouldn't want to then change it around.
As is enevitable in the cyclical nature of sport we will have a 'down period'. Thats when I would consider thinking about a rebrand excercise to try and boost interest when we arent making finals.
Someone mentioned our logo looks very 90's. Would you therefore advocate a change of logo every decade? Id hope not. Apart from the obvious costs associated you end up devaluing the brand as a whole by constantly changing it.
For me, Id leave it as is, for now anyway.
