Let me get two complaints out of the way..
1 - The video sucks
2 - I'm sure you've seen better brawls at a pee wee game
It is still awesome.
Here are some shots from the Raiders/Cowboys joint practice that broke out in two huge brawls. Police security was already beefed up because of gang concerns in Oxnard. In the first video watch the Raiders fan swing the helmet at the Cowboys player at the end.
