URBANDALE, IOWA — Filip Johansson buckled to his knees and eventually onto his back, then to his side.



At this moment, the Wild’s 2018 first-round pick was probably regretting answering the phone call from Wild management asking if he wanted to fly over to the United States for a week’s worth of skates with the rest of the Iowa Wild’s young, non-playing prospects as the team embarks on its first playoff appearance.



Tim Army, Iowa’s coach, gave the rest of his lineup — 18 skaters and starting goalie Andrew Hammond — the day off Monday to rest up after a 7-0 series-opening whipping of the Milwaukee Admirals the night before.



But the healthy scratches, guys like Dmitry Sokolov and Gustav Bouramann and backup goalie Kaapo Kahkonen, were summoned down to Metro Ice for an extensive practice, then a no-puck, no-nonsense skate-a-thon.



This wasn’t some kind of sick punishment by the Iowa coach.
