Bullshyt. In-game penalties are rare as hell - so far this year there's only been 14 penalties shot in 58 games, and even that number is distorted by the fact that they let Messi shoot a penalty in every game. Since two teams play every match, if your name isn't Messi than your team had less than a 1 in 10 chance of taking a penalty in any one game (11 penalties across 111 non-Argentina team games played).
On top of that, only 1 out of 16 players shoots that in-game penalty. So not only do 90% of the teams not shoot a penalty, but over 90% of the players on any one team aren't going to be the one shooting it even if they do. So if you're a World Cup soccer player there is less than 1 in 100 chance that you'll shoot an in-game penalty at any point in the World Cup.
Yet then you do this totally artificial penalty shootout where most of the players involved would never be picked to shoot the in-game penalty, where they all do it in an artificial atmosphere lined up one after the other, and where the goalie is in sync defending them instead of just getting one in the course of play. There's a reason why success rate in penalty shootouts is significantly lower than success rate in in-game penalties.
NONE of the players kicking penalties for the Netherlands has taken an in-game penalty shot at any point this entire World Cup. Same goes for Brazil in the shootout they lost. Same goes for Japan in the shootout they lost. Morocco hadn't taken a single in-game penalty all World Cup before their shootout, nor had Croatia before they shot 10 of them in shootouts.
It's ridiculous that half the World Cup semifinalists have already been decided based on something that resembles a practice drill more than any actual gameplay.
