American football expressions – what are they on about?

In case anyone missed Channel 5’s new MLS programme, David Beckham’s Soccer USA, last night, I have to comment on some bizarre sporting expressions being bandied about by Stateside commentators.
Each week, Soccer AM’s Tim Lovejoy widens our traditional football vocabularly with some typically cheesy but inventive ‘Americanisms’. They include, “He’s going to uncork it,” when a player is about to unleash a vicious shot and, “He’s got some wheels,” when referring to a player with a bit of pace.
But, my personal favourite is the use of the term “chicken wings”, which describes a scuffle among players using excessive arms and elbows (or what we might call “hand bags”) – brilliant!
Only in America I suppose – does anyone else have any idioms from across the Atlantic that they want to share for our amusement?
