I'm with you when it comes to sides like the Netherlands, who had no business being so conservative against Morocco. I mean, I guess that's what you get when you appoint Ronald 'Everton' Koeman, who has never been a dynamic coach, but still...
Even Japan, I thought they had the legs and the pace to run at Brazil, who have some holes in their defense.
But for Paraguay, that was the only way forward for them. They simply don't have the players to go toe-to-toe with Germany, even this 'worst German side in living memory' Germany.
Also helps when you have less to lose. The pressure at a World Cup in incredible, probably more than any other sporting event. Morocco going out to the Netherlands would have been a disappointment to them, but acceptable. It's a catastrophe for the Dutch, though, who see themselves as outside contenders to win the whole thing.
You saw that in the penalties taken. With less pressure (e.g. in a pro league game), the conversion rate sits somewhere between 75-85%. World Cup shoot-out pens typically convert at 65-70%, and the Dutch only hit 40% of theirs. All of that is fair enough if you had done everything you could to avoid pens in the first place, but they seemed to try and kill the game like Paraguay. As noted above, their manager was a great player, but has had a pretty spotty past as a coach...
Speaking of pens, I find it unreasonably satisfying when a shooter who indulges in stutter-step nonsense ends up missing like Kluivert and a couple others. Pick a spot, line it up, and put your laces through the ball. All this garbage taking advantage of the limitations on a keeper (especially now that they enforce them staying on the line) is so irritating in its lack of confidence. If you hit a ball well, it's unsaveable. My all-time favourite example of this was van Dijk eyeballing the Chelsea keeper in the League Cup final a few years ago after Kepa was using gamesmanship to try and put Liverpool off:
