2. Hooker
Hookers are a key position in attacking and defensive play. The name is derived from the fact that hookers use their feet to 'hook' the ball in the scrum; because of the pressure put on the body by the scrum it is considered to be one of the most dangerous positions to play. They also normally throw the ball in at line-outs. Hookers have more in common with back row forwards than props or locks only during line-outs as they have a roving role at line-outs. Hookers typically are a key player in the scrum as they are the main force pushing and resisting, although some teams give the responsibility to the props. In addition, hookers may act as an extra prop in the scrum, instead of contesting the feed, to wreak havoc on opposition feeds.
The hooker is assisted by the props in scrums and often leads a ruck. In defensive play, the hooker will regularly be the main attacker in most open-ended plays. In more complicated moves, the Hooker may remain a defence for the backs. Hookers are usually the leaders in most attacking moves and tend to control the forwards.
