If you lived in America what would be you favourite American teams that you would follow for :-

Football - Minnesota Vikings - been to see them and love Minneapolis as a city.
Basketball - Cleveland Cavaliers
Baseball - Some team with sox I'd imagine
Ice Hockey - The Mighty Ducks
Soccer - Red Bulls

Apart from the NFL, it's fair to say I don't really follow american sport that much, but I've taken a swing at the rest.
