The team that is the most focused and executes the best is the team that wins. That's usually the team that can handle the pressure of the situation.
I've never been very comfortable as an actor looking out into the audience; I always like to keep my focus on the other person. When you start playing out to the audience, it takes me out of it, because people don't do that when you're in life behaving with another person - you don't often look out, around you, in a presentational manner.
