Dave Portnoy, founder of Barstool Sports, sharply criticizes the United States Men’s National Team after a blowout loss to Belgium on Monday night. Multiple reports describe Portnoy posting an angry, curse-filled reaction on social media in which he calls the USMNT’s effort “pathetic” and “embarrassing.” Yahoo Sports characterizes his reaction as among the harshest he has offered during the team’s 2026 FIFA World Cup run, noting his long-standing support for the U.S. team. The coverage also indicates that his criticism extends beyond general disappointment into strong language directed at the performance itself. The New York Post similarly reports that Portnoy uses aggressive rhetoric while discussing the defeat, emphasizing that he viewed the game as a dominant showing by Belgium and a humiliating response from the Americans. Both sources agree the trigger for the outburst is the U.S. team’s loss to Belgium and that Portnoy’s reaction takes the form of public, emotional criticism soon after the match.
