British versions of American sporting events are rarely anywhere near as exciting as the real thing, we seem to have an inability to get going proper
Any boistrousness at such sporting events, especially anything with the 'Team GB' tag, normally comes from the fact that the crowd seems mostly to be pre-pubescent schoolkids screaming and screeching at nothing in particular, high on fizzy pop and the fact they're missing geography, watch any GB netball match and you'll see this at its worst...
If there are no screaming kids, it'll just be quiet and a bit dull. I used to go to ice hockey games hoping for some excitement and the potential for extreme violence, but it was just dull in the extreme, not even a face-off, let alone a punch-up....
