At their first practice Ms. Snow fields eleven inexperienced players and chaos breaks out. She abandons normal play for mistake soccer: use mistakes as tactics. She assigns roles—Fred must act within three seconds to shoot or pass, then fall; Theo stays in the opponent penalty to collect rebounds; Felix and Porter aim shots at Theo; Porter finds positions while Jim, nearsighted with a radar-like skill, calls who will meet rebounds so Fred and Theo act as a precise strike. Six others must sprint to cover gaps. Observers scoff; success now hinges on Jim's calls.
