Reid, a former assistant coach for the Kansas City Chiefs and the son of the team’s head coach, crashed into two cars in February, leaving a child seriously injured.
Reid told the police he had “two or three drinks” before slamming into a car that carried two small children last week. One is hospitalized with life-threatening injuries.
Analytics-minded observers have long argued against punting, but what may finally persuade N.F.L. coaches to go for it on fourth down is another postseason with high-profile successes.
