Use "replay" in a sentence
"In both cases, replay is permitted in one specific situation (a goal, or a home run) to determine one specific fact (whether the ball/puck went over the relevant line)."
"(And, to be fair, football uses replay for some calls for which replay is of little help.) There is very little judgment involved in such a call — unlike, say, calling balls and strikes or a balk — and replay can often provide a definitive answer."
"Accommodations are made to maintain the integrity of the game — such as waiting until a natural stoppage before reviewing the tape — but instant replay is still used to make sure saves are saves and goals are goals, and it works."
