As a coach, most of the time our alliance's analyst didn't do anything, and usually that was fine. We were mostly playing on tube-saturated fields, so the coaches did all the communication. I've found our HPs are usually pretty good about reading the field and keeping an eye on the coaches. This is usually faster and smoother, though if a coach is busy it's helpful to have someone else that can repeat it if I need to move on.

If we're exercising stricter tube control though (say the opposing alliance is all roller claws), it's nice to be able to yell "we need a square!" and have someone handle the HP communication while my drivers finish off the triangle and I'm clearing our next path with another coach or checking the field/grids/clock.

Time calls can be really helpful, and I made it a habit to tell the analyst pre-match what time we were planning on heading for the Tower (if we did that match, which granted wasn't often). My internal game clock's gotten pretty well ingrained over the years though, so constant calls tend to just interrupt coach-coach or coach-driver communication.

As for score calls, in general I usually find looking at the grid more helpful, since it shows how close they are to another logo, etc. If we decided pre-match that our strategy (usually like how early to head for the minibot towers) depends on the peg score difference as x time, the analyst can definitely come in handy.

TL;DR: Call relaying, time updates, and score calculations can help. Know how the game plays out, be good at communication, and be ready to do what your alliance needs.
