Thanks, IPW! I love sports topics, and used to work for ESPN, which was one of my favorite jobs ever!
I haven't gotten into football/soccer, because a) a team's success is too dependent on whether or not it is owned by a Russian billionaire, b) most of the matches are only available on Sky, which sucks (search my posts for "sky" and you'll find lots of colorful ranting), and c) it's too expensive/difficult to get tickets to games.
For example, I looked into getting Arsenal tickets when we lived in Finsbury Park, but you had to be a member of the club for £40/year, and all that did was give you the right to
bid on tickets season ticket holders didn't use. No thanks, Arsenal, I'll just get a t-shirt and be on my way. I realize I could just follow a local team or one from a lower league, but I'm not that motivated about it and have moved around too much to feel loyal to a particular area's team.
I'm following the World Cup more closely than I did in the US, but I imagine that's because it's more readily available and getting wider coverage in the UK. I'm still surprised, though, by how interesting I find it even after the US team was knocked out. (My nationalism is sad, I know.)
I watch F1 here in the UK, but I liked motorsports in the US, too, so I think that's really more of a "whatever is available" thing.
Cricket I barely understand, so that's out.
Even after coming to the UK, the only sport I follow religiously remains the NFL (go Cowboys!!). Somehow the difficulty of catching games has deepened my love for American football. Staying awake from 2am to 5am on a Tuesday morning, sitting on my couch with only the light of the television as England sleeps, wearing a Tony Romo jersey and watching the Cowboys live on Monday Night Football has only inflamed my passion for the game.
