Please can you explain (to the ignorant Englishman) what the NFL coaches challenge is ?
NFL Coach's Challenge
NFL coaches are allowed 2 "challenges" to an official ruling on the field, per game. Basically, if a coach doesn't agree with a referee's call / ruling on the field, he'll throw out a "red flag" (before play resumes) to force the officials to review the previous play via video replay. The refs can either confirm the original call or overrule (change) it.
For example, in a soccer (football) match, ball goes out of bounds and goal kick is called. Opposing coach disagrees and thinks a defender touched the ball before it went out of bounds (corner kick). Game stops, referees watch the video replay and can say NO, defender did NOT touch the ball, original call stands, goal kick. OR referee can say video replay evidence shows defender DID touch ball, so they'll change the call on the field and award the corner kick.
Another example could be for handballs. Ref doesn't see handball on field, but coaches do. Coaches could stop play and review video replay to see if handball did occur, etc.
