That's true, but it would help to have one person in case one of the team's robots breaks down, or something.

Instead of the two other teams having to think about what they do next, this person has already developed a plan, while the other 2 coaches are still executing the previous plan while the head coach comes up with a new plan for a few seconds (as someone previously mentioned, the coach just keeps the pressure off the driver; all the driver does is drive).

It'd be more of a passive role, I guess, until it's really needed.

But, I see your point in the idea too, and completely agree with you. However, depending on how good of a strategist (is that a word??) the head coach is, this plan could work really well
