If you'll recall, the IFL was originally about hokey team names, but towards the end of the promotion's existence, they just said screw it all and let the fighters rep their actual, real-life teams. Therefore, when Emyr Bussade and Jesse Lennox squared off, it wasn't so much the Denver Woodchucks versus the Austin Amoebas as it was a guy from American Top Team taking on a dude from Pat Miletich's camp. Which is fine, and how it should be.
Also how it should be: when a fighter is in danger of getting injured by a submission, he taps out. But Lennox had been pretty adept at avoiding the trouble his opponent put him in, so maybe he grew complacent or over-confident when they end was near. Whatever the reason, Lennox didn't submit to Bussade's bout-ending leglock so much as he let out a blood-curdling scream.
And trust me, I was sitting ringside just a few feet away. That scream curdled my blood.
So here it is, the worst bout-ending scream ever emitted from a fighter's mouth.
