 When this occurs, there is usually no blitz count and the all-time quarterback is usually never allowed to cross the line of scrimmage.Another common variation is the elimination of the field goal and extra point kick; this is usually due to the absence of goal posts and tees on the field as well as due to poor kicking skill by the participants.Some games eliminate kicking altogether, directing the teams to start each possession after a touchdown at the twenty-yard line, as if a kickoff and touchback had just occurred; other players prefer to change the kickoff into a "throw-off" or a "punt-off."
