Mario Williams is the demon of the defensive line

It's hard enough for quarterbacks to prepare to face the NFL's most intimidating pass-rushers, but Kansas City Chiefs passer Alex Smith could be forgiven for losing control of his bodily functions the moment he saw Mario Williams yesterday.

The Buffalo Bills defensive end took to the field wearing red contact lenses, and given the low temperatures in western New York yesterday, we can only hope there was also steam coming from Williams' nose to complete the look as he prepared to bull-rush towards Smith.

Although Williams, once the highest paid defensive player in the NFL, did get to Smith for a sack during the game, Kansas City came out on top, 17-13, thanks to two fourth-quarter touchdown drives.
