There are many team captains who are not on the drive team. Every tournament after alliance selection, the head referee meets with the alliance captains - those who picked the alliance. One of the first questions the head ref should ask is if everyone there is on the drive team. More often than not, at least one of the alliance captains is not on the drive team, in which case the alliance captain is responsible to give all the head ref's instructions to the drive team.

And I realize that the person who picks the alliance may be the scouting captain, another position althogether.
