I was looking at some a soccer teams website when I decided to go look see if any variations were available just a couple of days ago. here are a couple i found:

nashvillepredators.com - official site
nashvillepredators.net - mine

lagalaxy.com - official site
lagalaxy.net - mine

metrostars.com - official site of NY Metro Stars
nymetrostars.com - mine

I also got a couple european teams .us domains, but these three are the ones I was really surprised that I was able to snatch! some decent buys here maybe???
