The mantra "Why not us?" has become a rallying cry for the U.S. men's national team (USMNT) as they navigate the FIFA World Cup, a belief that has permeated the squad and resonated nationwide. This optimistic outlook is actively cultivated by 54-year-old Argentine manager Mauricio Pochettino.

"We all believe in it," said Tim Ream, the 38-year-old U.S. defender and team captain. "We've all talked about it. We all say it: 'Why not us?'"

The sentiment is now a visible reminder for the players, displayed prominently in their team accommodations. "It's taken hold," Ream added. "It's all over our hotels, it's all over our meeting rooms and our spaces. It's a reminder to continue to believe, and we are fully ingrained in that and continuing to believe that." Mention of Pochettino's growing connection to American culture, including his singing of "Take Me Home, Country Roads" after team victories, underscores the unique environment he has fostered. This cultural integration appears to mirror the team's growing self-assurance on the world stage.

The team's performance and burgeoning confidence suggest that this belief system is more than just words; it is a tangible force driving their World Cup campaign. The "why not us?" mentality reflects a team ready to challenge expectations and compete at the highest level.
