It is virtually the same as the statistic that some football leagues refer to as combined net yards.
Progress can be made during play by the offensive team by advancing the ball from its point of progress at the start of play known as the line of scrimmage or by the defensive team after taking possession of the football via a change of possession (such as punt, kickoff, interception, punt block, blocked kick or fumble).
When the offensive team advances the ball by rushing the football, the player who carries the ball is given credit for the difference in progress measured in rushing yards.
[4] Neither of these totals makes clear how they record yards from blocked punts recovered, blocked field goals, and missed field goal returns.
