PARIS -- Start at the end, and maybe we'll begin to understand -- or not.
Moments after the final whistle of a 0-0 draw between Portugal and Austria at the Parc des Princes in Paris, the players are shaking hands and chatting as they do normally do postgame. A guy dressed in black sprints onto the pitch from the Austrian end and makes a bee-line toward the knot of players by the center circle. A single, solitary steward chases him. That's right: Just one guy pursues the interloper while everybody else stares.
He reaches Cristiano Ronaldo, and by this point, there are team officials and others around.
