Like most fans, I did not choose to be one. I became one after watching Marino. One of my two sons loves football and became a fan. My eldest son prefers boxing and watches a game now and then but is not a die fan and is probably happier for it,
Being a fan is not all that great. You are spending a tremendous amount of time discussing and maybe obsessing about something you have zero control over. There is a lot of satisfaction when the team wins which is offset by the pain you feel when the team loses. And only one team out of 32 will end the season in a winning note. Miami last won a SB 63 years ago. I should know better but I am hopeful that the season will be a lot better than expected and the beginning of another glorious run. 1971 all over again.
I would not advise anyone to become a die hard fan of any professional sports team. But if it happens the Golden Rule is to keep a healthy sense of humor. As one fan aptly stated, at least we are not the Jets.
