The players skated around Tuesday afternoon at Wukesong Sports Center without their helmets and — briefly, mercifully — without their masks, stopping and smiling for the camera that would capture the official team portrait of the 2022 U.S. Olympic women’s hockey team, not to mention their own camera phones that were tucked under pads on their hips or their shoulders. After the large group photo came the subsets: first-time Olympians in one shot, the goalies in another; University of Minnesota players followed by those from the University of Wisconsin — rivals in everyday life, teammates here.
