INGLEWOOD, Calif. — Every coach at the World Cup says the knockout rounds are all that matter. 

Very few are willing to prove it. 

Mauricio Pochettino did. 

After the United States had already wrapped up first place in Group D, 10 new starters walked onto the field at SoFi Stadium, with Weston McKennie standing alone as the only player to start all three group-stage matches. 

The result was a 3-2 defeat that snapped America’s perfect start and denied the hosts something no U.S. men’s team has ever accomplished at a World Cup: three wins in three group-stage matches. 

Was it the right call? 

The honest answer is we won’t know until July 1 at Levi’s Stadium. 

If the U.S. comes out sluggish against Bosnia and Herzegovina, disconnected and lacking the chemistry that overwhelmed Paraguay and Australia, Thursday will be remembered as the night Pochettino interrupted his own momentum. But if his first-choice lineup looks quicker, sharper and fresher over 90 minutes because it had an extra week to recover, then this loss becomes little more than the price of thinking several moves ahead. 

There were undeniable benefits. 

Instead of rushing Christian Pulisic back from an injured left calf back, Pochettino eased his superstar into the tournament. Pulisic entered in the 58th minute and immediately transformed the American attack. The passing became cleaner. The movement became more dangerous. The U.S. suddenly looked capable of creating chances from open play instead of relying almost exclusively on set pieces as they had in the first half. 

The match also served as an invaluable audition. 

Sebastian Berhalter seized it, delivering dangerous service on corner kicks and scoring a goal. Auston Trusty found the net as well and looked composed before rolling his ankle, an unfortunate reminder of how quickly fortunes can change in tournament soccer. Had that injury happened to Chris Richards instead, the Round of 32 could have looked dramatically different. 

Others didn’t strengthen their case. 

Mark McKenzie and Miles Robinson struggled with Turkey’s movement inside the penalty area. Matt Turner had an uneven performance in goal. The midfield offered little protection, and defensive lapses repeatedly left runners unmarked. 

Perhaps the most important victory never appeared on the scoreboard. 

Richards. Tyler Adams. Folarin Balogun. Antonee Robinson. 

All four entered the night carrying yellow cards. All four emerged healthy, suspension-free and fully available for the knockout stage. That alone may ultimately justify Pochettino’s thinking. 

History has shown that chasing milestones can become a dangerous distraction. 

The 73-win Golden State Warriors became synonymous for surrendering a 3-1 lead in the NBA Finals. The 111-win Dodgers are remembered more for their stunning postseason exit. World Cups operate under the same reality. Nobody remembers that Argentina lost to Saudi Arabia in 2022, they just remember Lionel Messi lifting the trophy. 

Momentum is real. 

So is fatigue. 

Pochettino chose fresh legs over optics. 

“We got an opportunity to rest,” Balogun said of the decision. “The games are so intense. Getting the extra days of rest is definitely going to be a positive for us.” 

Pochettino made a calculated bet that sacrificing one meaningless result would increase his odds of winning the games that actually define legacies. 

Whether that decision was brilliant or misguided won’t be decided by a Thursday night loss in Los Angeles. 

It will be decided 350 miles north in Santa Clara, Calif., when the United States walks onto the field with rested stars and no more second chances.
