Winning changes everything. It turns the lazy fan into the fair weather fan. The only reason they care now is because everybody else is talking about it. Interest rises with social dialogue.
But having more supporters (even if they’re temporary) gives the original supporters more to cheer about. The real fan’s duty is to show the newbies what real passion is.
Losing hurts. That’s what care does to its followers. But losing is also part of the larger story. Living through the ups and downs and still showing interest and support are what being a ‘real’ fan is all about.
