James Anderson's action is a purist's delight. If Michael Holding was called 'Whispering Death' because of his beautiful action, Anderson's action is all about extracting maximum output while putting minimum effort. He runs in smoothly, doesn't have a big side-on jump, and makes a perfect landing. He finishes his action with clinical precision.
