What does being the "R" mean to you?

[Damian]

During our summer meeting, one break out discussion was raising your game to a higher level. We had a spirited discussion on what it means to be the "R". Some ideas were that you knew everything happening around the court. Others were that you helped your partners raise their level.

With all of the collective knowledge on this forum, I would like to hear what some of you have to say about this.
