Just some of my thoughts...
-Portugal had 3 shots on target (5 off target), one post, and 5 corners. Plus, they scored in the extra period time period to win the game, 1-0 over France. The Final did not go to penalty kicks. Why is that even mentioned here? What's the relevance?
-Some teams are more defensive than others, and they are constructed to systematically, as a team-unit, smother the opposing team's individual attacking talents and pull out either a draw or that one opportunistic chance to win the game.
There's no wage or transfer cap in European football, nor any kind of barrier to teams like Spain or Germany developing international talent, so you will always see attacking styles contrasted with defensive-mentality. It's unreasonable to expect teams that cannot match the attacking talents of the other team to try and play that style and win. They will almost certainly lose. I'll take winning over being entertaining and appeasing fans, any day.
-PK's are done throughout the football world and globe, in like every major tournament. Making this a case against the MLS is....weird? Additionally, there used to be 'Golden Goal', or sudden death OT. It was widely regarded as a failure though, hence the change. Teams were way too afraid to go out and attack, preferring to keep their players in consistent positions, taking almost no chances. So you got an extremely dull spectacle with defensive football being prominent.
