Kilmarnock. My hometown team, been going to Killie games since I was a boy, will probably still be going till my dying day. In the English league, I have always supported Liverpool. When I has a lad in the early 80s, Liverpool were the best team in Europe, and always had some great Scottish players. Also have a soft spot for Juventus in European football.
And obviously Scotland in international football, but there is no chance of us ever winning a tournament, so in the World Cup and the Euros, i always end up cheering on Italy.
Washington Redskins! Back in 82, when the NFL got its first big push in the UK, my dad got me a Redskins poster and my brother a Dolphins poster, and they have been our teams ever since! I remember as a schoolboy, staying up all night to see us win 3 Super Bowls, and being completely stunned when the Raiders hammered us in Super Bowl XVIII.
I also cheer on the Miami Dolphins as a second team, again back to the 80s, and one man, Dan Marino. Nothing in the world was as cool as Dan Marino in his prime! And we had never saw anything like him over here, in that gorgeous white and aqua uniform in the blazing Florida sunshine, blasting that ball downfield like a cannon! He was the reason the Dolphins were easily the best supported team in Britain back in the day, and even now are still right up there despite not having won a title in over 40 years.
New York Mets. About a decade ago, Channel 5 would show live MLB games through the night twice a week, so when I got up early for work on Monday and Thursday mornings, I would catch the last few innings of a game before heading out. I got into the sport so much that I recorded the games and watched them when I got home. Usually it was east coast teams that were shown, usually the Yankees, Red Sox, or Mets. I have no idea why I preferred the Mets, maybe the did not seem as stuck up as the other two, maybe it was from Seinfeld, but the Mets were the team I liked!
Alas! Channel 5 lost the MLB contract, and no free to air broadcaster picked it up, so I have fell away from baseball.
