Personally, I think it should be the opposite. A good drive team shouldn't have to be "babysitted" by their coach. Maybe early in the season once things are getting started you could get away with that, but as time goes on, teams get better. After several matches or an entire regional, your drivers should know that once they cap they go back to the human player station or auto loader and make sure that the goals you decided before the match need to be focused on are capped.

Eventually they should do it on their own.

Once the drive team has it under control what they need to do, that frees up the coach to keep an eye on the opponents, the partners, the field and most importantly, the clock. Really, the only time the coach should have to come into play and direct them is when something unexpected happens (like a team sneaks down into your area and breaks up your home row, something on your robot breaks, or something happens to your alliance partner) or if you need to drop everything and get back to your starting area for that 10 bonus points.

Anyway....to sum it up, once your drive team gets what they do down pat, the coach should shift his attention away from the drivers doing their job and more towards just focusing on the entire field.....that's how you win big matches.
