Read the article. It's not saying MLS is soooooo good. It's saying MLS is making great strides, improving in popularity but isn't going to compete with the big 4 Euro leagues any time soon.
And you're wrong about those aging players. Some fairly big clubs from those big Euro leagues would happily have taken Ljungberg, Henry or Marquez, but they chose MLS instead.
If more people gave it a chance instead of arriving at these daft conclusions before even taking in a game, MLS would truly be a major player in the soccer world.
