text: In football, the captain doesn't really have the role of coaching players off the field. It is more of a leadership role on the field, during play. There is the arguement that he can only have a direct input to the defenders as he can't move around the field and tell the strikers etc what to do, but a goalkeeper can see the game happening in front of him - sometimes with little to do but observe. If the player has a strong, motivational side to his character, then there is no reason why a goalie in football shouldn't be ideal for the captain's armband.
