NFL规则防止在熊教练的挑战中使用边界摄像头,引起对公平性的关切。 NFL rules prevented the use of a boundary camera in a Bears coach's challenge, raising fairness concerns.

在NFL第12周的比赛中,芝加哥熊教练Matt Eberflus挑战一场比赛,但由于NFL规则不允许使用边界摄像机进行审查。 In a Week 12 NFL game, Chicago Bears coach Matt Eberflus challenged a play, but the use of a boundary camera for the review was not allowed due to NFL rules. 联盟允许官员使用所有工具, 包括边界摄像头, 在评分比赛、更替或较晚比赛时使用, 但不是为了教练的挑战。 The league permits officials to use all tools, including the boundary cam, during scoring plays, turnovers, or late-game calls, but not for coaches' challenges. 这种不一致导致混淆和对公正性的关切。 This inconsistency has led to confusion and concern over fairness.
