fly-half - rôle and morphology
A fly-half is crucial to a team's game plan. The fly-half is usually the one who calls set moves, or makes tactical decisions. Fly-halves need to be quick-thinking in a game, such is the speed at which a situation can deteriorate, and need to be able to communicate with all the backs and adapt them to the attacking or defending situation. Usually, the fly-half is the kicker of the team, a role often shared with the centres or fullback. Many fly-halves are goal kickers, and make most kicks for the team, whether it's tactical, or for touch.
