The report says Kelce compared American support with the energy often found in British football grounds, where songs can carry aggression, humour and a clear sense of identity.
That contrast touches a long-running question around the United States men’s team: can the atmosphere match the ambition of the tournament? American football crowds have grown more visible and committed, but the culture remains less established than in countries where terrace singing is woven into the sport’s history.
Kelce reportedly argued that nations such as Brazil do not need to talk themselves into believing they can win. His point is simple: confidence should sound instinctive, not rehearsed.
Former United States international Landon Donovan agreed that supporters can raise their game.
“Obviously we have creative people in this country,” Donovan said. “We just need to get together and figure it out. We agree, it's got to be better.”
That endorsement gives the criticism added weight. Donovan understands the pressure of representing the national team, while Tim Howard, who was also part of the discussion, knows the difference a hostile or passionate crowd can make from the pitch.
The reported meeting with Bosnia and Herzegovina offers an immediate stage for the debate. A knockout match should provide natural drama, but the challenge for American supporters is to create a sound that belongs to them rather than borrowing from established football cultures.
The next storyline will be whether Team USA’s fans answer Kelce’s call-and whether a more forceful soundtrack can help turn tournament excitement into genuine home support.
