I'm a Hawthorn fan. My grandfather played for the team in the 1930s and 1940s (when they weren't good at all - he was something of an Archie Manning figure during those early years). More recent times have been very kind to Hawthorn fans though with 13 premierships since 1961 including four since 2008. I tend to go to all our games in Victoria and a couple of road trips annually too. Hard to separate the Hawks and the Saints as my #1 sporting love - probably the Hawks just - but the good thing is there is minimal overlap between the AFL and NFL season.
I kitted up @OutlawSaint and his buddy in Hawthorn baseball caps in Atlanta prior to the TNF game against the Falcons in November too. Gotta spread the fandom.
