For all of the USWNT’s attacking verve, there are question marks aplenty about what happens when other teams attack them. O’Hara, who’ll start at right back, has been hampered by an ankle injury over the last few months, and Dunn, her counterpart at left back, is a converted attacker, not a true defender. Sauerbrunn is back again to start at center back, and while her likeliest back-line partner ― Abby Dahlkemper ― is super-talented, this is her first World Cup. Same goes for goalkeeper Alyssa Naeher, who was on the roster in 2015 but didn’t play. The U.S. struggled to keep quality opponents off the scoreboard early in 2019, conceding seven times in three matches against England, Australia and Japan this spring. They were better in World Cup tune-ups ― the U.S. hasn’t conceded a goal in four matches since shipping three to the Aussies in March ― but those matches were against lesser foes. The Americans like to dominate the ball and attack at will, but eventually they’re going to run into the sort of teams capable of punching back.
