J. Scott Shain has been a youth football coach for years. The Racine Raiders, a minor league football team, allows youth football teams to play short scrimmages during the Raiders’ halftimes. Shain’s team was playing, as were numerous other teams, on the Raiders’ field. To accommodate all of the teams, the Raiders’ field was subdivided into smaller fields with little to no space in between the fields. While Shain was coaching on one of the small fields, two players involved in a play on the field behind Shain collided with him, causing him to injure his knee. Shain filed suit against the Raiders, Racine Youth Sports, and their insurers, alleging negligence. If you were defense counsel in the case, what defense would you use? What would you need to prove to win your case? Shain v. Racine Raiders Football Club, 726 N.W.2d 346 (Wis. Ct. App. 2006).
