So if I understand you and Matt correctly you’re saying the talent level was so low it failed to execute Berhalter’s system competently enough to avoid bunkering down under pressure.
I’m not disagreeing, I’m second guessing my ability to assess tactics and reconcile talent.
Not really...
If you're going to look at what Berhalter's system is trying to do its this:
You can essentially break the field down into a grid of 30 squares (to simplify it -- they're fluid, they obviously get compressed during game play, but it makes it easier to visualize). Five lanes going the length of the field (sideline to edge of the 18 on both sides and three lanes through the center of the field). These are vertical spaces. Also think of 6 cross sections going from our own endline - to the top of the box, top of the box to halfway to midfield, halfway to midfield to midfield, and then repeating on the other end. These are called your lines or horizontal spaces. They essentially create a grid on the field and each square in that grid creates a space -- guys like Pep Guardiola actually set up these grids (in their own variation) on their fields when training this way.
The way that Greg wants to play in possession (and think of this for all but the most offensive two horizontal sections of the field) is that you'll never have more than one player in any space, more than three players in any of the horizontal lanes, more than one player in any of the two spaces north or south of the ball, and always at least one player in a diagonal space from the ball.
He does this because he's looking to gain a numerical advantage in each area of the field that he is playing the ball in. For example, every time a US keeper gets a ball you're going to see the same thing happen. Your left center-back will split out wide left, your right center back will split out wide right, and (depending on if you are playing a 3 or 4 across the back) your central midfielder (think of when Tyler Adams will drop back between your CBs in a 4 across the back) or central defender (James Sands these last few games) will drop back centrally to the top of the 18 -- you'll almost always see the goalie with the ball in the six yard box and a line of three players across the 18. The reason that they do this is that even if the defense is to bring pressure with each of its 3 forwards/attacker, you will still have a numerical advantage in this area (if they brought more -- you could overrun them in the midfield, no one wants that). The thought process is that 3 defensive players should not be able to cover 4 offensive players. It's why playing the ball with your feet is such an important part of being a Euro goalie and why Steffen isn't playing more regularly -- because he is an world-class elite shot stopper, but he still struggles in possession.
That part is easy enough. I'll use our base 4-4-2 example (with who I think our core players will be) to explain the next step.
After Steffen gets the ball, Brooks breaks out wide left, Richards breaks out wide right, Adams drops centrally to receive the ball. Your next move (and this is why Brooks is constantly screaming at Dest -- because he's awful with this stuff) is that your outside backs move up offensively and need to watch where McKennie is dropping off on Adams's diagonal position. If McKennie is dropping off to Adam's northern diagonal right, it's the left back's responsibility to rotate into Adam's northern diagonal left. Your left back is now playing inside and ahead of your left centerback -- it's what's called your rotation. It's basically why in these systems you often see players that can appear out of position. The tough thing to get used to though is that it's not always that simple. If your left wing (Pulisic) drops back to help in possession (and ends up on Adams northern left), you all the sudden have 4 guys on the same horizontal (Left back, Pulisic, McKennie, Right back) -- that's basically the green light for your left back to get forward and into a more advanced offensive horizontal space. There are probablu thousands of different scenarios like this that players can find themselves in but they're always supposed to find the right position to create a simple pass or second pass in possession. Someone like Pep would say that every defensive structure would have the perfect movement into and out those spaces - it's why his game plans are 2 or 3 hundred pages long. Someone like Tuchel would say Pep overthinks the game and that players should be trained to organically move into space and it should just be a second nature.
You basically play this positional game of trying to achieve a numerical advantage throughout this grid as you move up the field.
What I think people are most confused about in this system (outside of players still trying to learn their positioning), is how you'll eventually finish in the final third. The reason that you are running this positioning based system is that the ball will always move faster than the opposing players. So if you can overload one area of the field, you can try to open up space that fits your offensive philosophy. If you have someone like Messi, you devise a plan to create space for him in the horizontal area of the field between your opponents backline and defensive midfielders (false 9). You can then hope to get him the ball in that space, make a central defender step up "between the lines" and either exploit a defender weaker than your offensive player or utilize the vacated space from the defender who stepped up "between the lines" with what's called a "third-man" run, where a teammate runs into that open space vacated by the defender that stepped up and is hopefully open to receive a pass. If you have someone like a Haaland or a Lewandowski, you try to devise a way to find them space between the opponents defenders -- it's called a half-space. If you have someone like Josh Sargent, or Gyasi Zardes, or Matthew Hoppe... ??? I'm not really sure what we're trying to do in our offensive third... One would assume though, we may try to find a way to move the ball up the field and move the defense in a way to isolate someone like a Puli against a wing defender who may not be as strong as an on the ball defender, creating a scoring opportunity, but we've really struggled here and seem to lack a philosophy in the final third.
Most possessions don't end is a shot or goal though -- even simple possession in soccer is really, really tough. Immediately after the transition from offense to defense (for example, we turn the ball over), in this system, we still should have a the advantage with the number of players in that area on the field. The thought process is that if you quickly throw all of your players at the ball, and at opponents that could receive a simple pass, in an area of the field where you already have a numerical advantage and win back possession quickly, you'll have a positional or qualitative advantage on the field going forward. It's the core tenant of every Red Bull team (from my buddy's U-8 team in New York [NJ] to the way they play at Leipzig.) It's the reason why someone like Tyler Adams is so valuable in this sort of system. This may be inaccurate from memory -- but I think if you look at the goal that we scored against Mexico in added extra time, it was the result of exactly this. I believe we turned the ball over in our own half, quickly pressed the ball, recovered it, and had a mile of space open up the right side of the field which eventually led to our penalty -- it's exactly what this system is made up to do.
Berhalter's system (and a lot or club systems) is basically a twist on the dutch version of total football with a more aggressive defensive philosophy.
That's why it looks like there is such a discrepancy between the players on the pitch right now. James Sands has been playing this system for the last 7 years of his life under Patrick Viera and Pep Guardiola's former top assistant at Barca, Munich, and Man City, Dome Torrent -- it's why I said earlier that I thought we'd find not only a missing link in our back-3, but also our most like-for-like replacement of Tyler Adams this tournament -- he plays both very well. Many of these guys though are 22 years old, have been playing in the same academy since 17, and are used to a less complex, more static possession system where the same players are in the same positions all the time -- it's basically what led to Canada's best scoring opportunity in the beginning of the second half where we errantly lobbed a backpass to where you'd normally find your holding midfielder in a more static formation that Larin (?) intercepted and mishit from 20 out.
The issue Berhalter is going to run into is that this is a pretty good (and widely used) strategy across the club level. Teams press the ball more, hold a higher line, and generally play a more aggressive style of defense -- the name of the game is to defensively force your opponent to make an error and capitalize on it. This is why offenses are set up to exploit a more aggressive defense. In soccer at the club level, defensive styles control the tempo of play. At the international level, teams have less time together, their defensive tactics are less complex, and you'll have a bend, but not break defensive motto -- including holding a deeper back-4 line like what you see in many of the South American leagues that have a more wide-open level of play and playing a softer press. Defenses are harder to move around -- it's the classic frustration you see when teams 'bunker'.
Anyway, that's kinda (I believe) why we look less sharp than expected right now. For 90% of these guys it's a different system than they are used to, the movements off the ball are complex, they aren't pre-determined like a basketball or football play -- if you haven't played with players before you'll be less likely to understand their unscripted, off the ball movements and they'll make more mistakes in their movements as they learn the system.
Not gonna lie though -- I typed this up during the commercial breaks of the NBA final after a day of heavy day drinking celebrating some professional wins, but hopefully it will vaguely shed some light on what Greg is trying to do, and actually did very successfully -- at least in the MLS and why it's not what everyone has hoped it would be thus far on the national team stage.
