We have had success using a single driver. multiple drivers, an adult coach, and student coaches.
It depends on where your team is experience-wise if you ask me.
This year, I went in as coach until my team president told me he wanted a classmate to coach on the field.
After a couple of matches, he said that he wanted me back out there so I became the "strategist" for the rest of the competition.
I typically trust the team leaders to make the call in this manner.
In Triple Play, there are enough teams that do not understand the game well enough to make it an easy task to strategize effectively so it is good to have someone out there to assert what he/she thinks needs to take place during the round.
