I guess that's the theory, and by having more of the ball and territory we might say, concede less set pieces.more and better attacking automatically improves the defence.
However at the moment we regularly have 5 back, and the wing backs don't often get caught up the field. We're harder to counter on that we might be if we commit more players forward (and when we did get more forward, see Northampton's excellent counter goal).
Plus at the moment, the two centre mids don't always fly forward and the wide players in the front three are expected to work hard and back in the channels. A changed, attacking system might affect some of that.
