Seen the video before and its pretty good, too bad I couldn't understand a word said by them.
Biggest game I was at was a small regional scenairo and I think we had about 200 people total so your looking about 100 people per team. Then I've been to local scenairos at my local field which get about 80-100 people each time.
I wanna try and goto Blanding in Florida for their December game and then that should be the biggest scenairo game I've been to.
And here is a link to the video just incase anyone has difficulty locating it.
