Soft but I am ok with a PK. Keep your arm down and see if that guy gets a header onto the ball. He probably doesn't. But if he did have a shot at it, who knows maybe they score. And then walker gets killed for not doing more to put the attacker off. Its a no win situation for him, but thats the reward for tunisia for whipping in attacking ball.
Offense should be allowed to take desperate attempts at goal. Its good for the game. Good for long shot teams scoring, and good to break down parking the bus. If you want to defend, do it at the spot of the cross. Midfielders/wingers should hustle to shut down crosses. If they can't do that and the cross does get into the box, then it should be jump ball for the header. I don't like it when defense for a CB means just obstruct the run of the attacker to the spot where a header could meet the flight of the ball. I understand you are allowed to stand your ground, but when you actively take two steps to the left only to cut off a run, thats obstruction to me. No different to me then cutting off the run of a guy who just megged you. Your getting beaten and in desperation you obstruct the play.
