 By quickly substituting and setting up for the next play—often within 5–10 seconds after the last play despite being afforded 45 seconds—the Bengals hindered the other team's defense from substituting situational players, regrouping for tactical purpose, and resting.In response the NFL instituted rules allowing the defense ample time for substitutions when offensive substitutions were made.The hurry-up tactic was used by the franchise during the late 1980s while Sam Wyche was the coach.
