What is Rugby?

This article from Wikipedia discusses Rugby Union, of which the CSULB Rugby team plays.

Team positions: Fullback

The full back stands back to cover defensive options as a 'sweeper' behind the main line of defence removed from the other backs. As the last line of defence, they require good tackling skills.

They have to catch the high kicks referred to as "up and unders", "Garryowens" or "bombs". Having taken a catch, the full back may choose to return the kick, and so good tactical awareness and kicking skills are required. Increasingly often, full backs are used to start counter-attacking moves from depth. Thus, they need have to have excellent attacking skills, pace and open field running prowess. In attack, the full back may also run into the back line at pace, providing an extra man, either a decoy runner or an extra man creating an overlap.

Notable fullbacks include Jason Robinson (England and Lions), Don Clarke (New Zealand), Christian Cullen (New Zealand), George Nepia (New Zealand), Bob Scott (New Zealand), JPR Williams (Wales and Lions), Chris Latham (Australia), Gavin Hastings (Scotland and Lions), Serge Blanco (France), Percy Montgomery (South Africa) and Matt Burke (Australia), Peter Hewat (Australia), Josh Lewsey (England and Lions), Gareth "Alfie" Thomas (Wales and Lions), Geordan Murphy (Ireland and Lions), Girvan Dempsey (Ireland and Lions), Chris Paterson (Scotland) and Jonathan Webb.
