Pressure or Stress?

Whether attacking or defending the idea is to control the pace of play.  Modern defenses play a pressing style that seeks to speed of the decision making process of their opponents.  Modern attacking schemes are relying evermore on making a set zonal defense side to side while probing developing in and out of developing seams until a breakthrough to goal can be achieved. This type of attack applies pressure to the opponents defense.

My question to you, is pressuring the opponent enough to turn the tide in a contest?
