To be fair, most of the matches haven't been all that entertaining. To put it in hockey terms, it's kind of like watching Nashville play hockey against New Jersey. Or, in football terms, it's a pre-west coast offense match with two running teams who both have excellent defenses playing a field position game. Watch how the teams move the ball through the midfield and into the other team's side of the field. They'll try one side, pull it back, try the other, pull it back, then maybe up the middle. They might turn it over and then the other team tries. The teams are probing for a weakness or looking for a defender to make a mistake. An effective counter is so lethal because it breaks the static nature of defense and forces them to defend on the run. It's a very effective tactic. Here's a textbook example from last year's Confederations Cup by the US. Rather than obsess over scoring chances and goals, look at each game through the lens of time. 90 minutes. It's a long time and there is strategy involved. Like a pitcher will set hitters up for later in a baseball game, so too will good soccer teams. You might play conservative in the first half -- you try to force the other team to break you down while seeing the tendencies of their defense. Then in the second, you adjust your tactics to take advantage of their weakness. Substitutions are about changing the game, usually. A guy like Clark for the US is a defensive central midfielder, whereas Torres is a great holding midfielder with excellent passing. It's also about conditioning and stamina. Around 65-75 minutes, players are getting tired and what wouldn't work early in the game might work at the end. Think pitcher's duel.
