A style of bowling attack where balls are aimed towards the leg side, utilising several close-in, leg side fielders. The aim of leg theory is to cramp the batsman so that he has little room to play a shot and will hopefully make a mistake, allowing the close fielders to prevent runs from being scored or to catch him out. Leg theory is considered boring play by spectators and commentators since it forces batsmen to play conservatively, resulting in few runs being scored. See also fast leg theory and Bodyline.
