Blocking a kick in the NFL is often times a turning point in a game….whether it be while blocking an extra point….or blocking a punt….as blocking an extra point obviously saves a point on the scoreboard….and cuz if a team is punting….it means they are typically at least 50 yards away from scoring….and in return, that means that there is a good likelyhood that the team that blocks the punt will receive the ball in good field position to at least score on a field goal….if not a touchdown.
As evidenced by this NFL Films piece titled Block That Kick….this is a part of the game that the NFL focuses on greatly….in practice and in a game.
