The intrigue: American players showed the creativity, crisp passing and kind of nifty one-on-one moves that U.S. fans have been accustomed to seeing from traditional soccer powerhouses in Europe and South America.Threat level: Paraguay resorted to rough play at times, racking up five yellow cards. Star U.S. forward Christian Pulisic was subbed out at halftime as a precaution after getting kicked in the left calf.Stunning stat: U.S. center-back Chris Richards completed all 83 of his passes, the most passes with 100% accuracy by any player in a World Cup game since 1966, per the sports analytics company Opta.What's next: The U.S. plays Australia next Friday in Seattle.
