Heh. I once asked a couple of British friends on a forum about cricket and one said, "you might just skip to the nap half way through."
Of all the sports to import I never imagined cricket. They might carve out a niche.
The others:
Rugby has a good chance of catching on. Everybody wants to see NZ play.
La cross has gained popularity on a grass roots level. They started a youth league here a couple of years ago and it's gaining popularity. (Which is amazing because the Midwest is usually behind by 5 - 10 years.) It looks like a good sport.
F1 racing has caught on in the US and is growing rapidly, or so I'm told. This is a good thing, I think.
