Stat_ID Name Comment
1 Rushing Yards - Minus Used in addition to the other Rushing stats so that total minus rushing yards can be calculated.
THIS STAT IS NOT IN USE.
2 Punt Blocked (Offense) Punt was blocked.  A blocked punt is a punt that is touched behind the line of scrimmage, and is recovered, or goes out of bounds, behind the line of scrimmage.  If the impetus of the punt takes it beyond the  line of scrimmage, it is not a "blocked punt."
This stat is used exclusively of the PU, PU_EZ, and PU_TB stats.
3 1st Down Rushing A first down or TD occurred due to a rush.
4 1st Down Passing A first down or TD occurred due to a pass.

10 Rushing Yards Rushing yards and credit for a rushing attempt.
11 Rushing Yards, TD Rushing yards and credit for a rushing attempt where the result of the play was a touchdown.
12 Rushing Yards, No Rush Rushing yards with NO rushing attempt.  This will occur when the initial runner laterals to a second runner, and the second runner possesses the lateral beyond the line of scrimmage.  Both players get rushing yards, but only the 1st player gets a rushing attempt.  The rule is that the last player to possess the ball behind the line of scrimmage gets the rushing attempt.

17 Passing Yards, No Pass In SuperStat, this code was used when the initial pass receiver lateraled to a teammate.  It was later combined with the "Passing Yards" code to determine the passer's (quaterback's) total passing yardage on the play.  IN OUR SYSTEM, THIS CODE SHOULD NOT BE NECESSARY.
18 Passing Yards, TD, No Pass Passing yards, no pass attempt, with a result of touchdown.  (See previous code.)  THIS CODE SHOULD NOT BE NECESSARY IN OUR SYSTEM.

30 Punt Inside 20 This stat is recorded when the punt RETURN ended inside the opponents 20 yard line. This is not counted as a punt or towards punting yards.  This stat is used solely to calculate "inside 20" stats.  This stat is used in addition to either a PU or PU_EZ stat.
31 Punt Into End Zone SuperStat records this stat when the punt is received in the end-zone, and then run out of the end-zone.  If the play ends in the end-zone for a touchback, the stat is not recorded.
This stat is used exclusively of the PU,  PU_TB, and PU_BK stats.
THIS STAT DOESN'T MAKE SENSE TO ME BECAUSE IT'S USUALLY CONSIDERED A GOOD PUNT IF THE BALL IS KICKED HIGH ENOUGH TO PREVENT A RETURN.

63 Miscellaneous Yards This is sort of a catch-all for yardage that doesn't fall into any other category.  According to Elias, It does not include loose ball  yardage.  Examples are yardage on missed field goal, blocked punt.  This stat is not used to "balance the books."  No such accounting occurs.

Unlike a Punt, a field goal is STATISTICALLY blocked even if the ball does go beyond the line of scrimmage.
72 Extra Point - Good Extra Point Good.  SuperStat uses one code for both successful and unsuccessful extra points.  I think it might be better to use 2 codes.

84 1/2 Sack Yards (Defense) Sack split equally between two players.
ELIAS WILL GRANT 1/3 SACKS, AND WILL NOT PLACE ANY LIMIT ON THE NUMBER OF PLAYERS AMONG WHOM IT WILL DIVIDE A SACK.  HOW TO HANDLE???

90 1/2 Safety (Defense) This stat was used by SuperStat when a 1/2 Tackle resulted in a safety.  This was in addition to a 1/2 tackle code.
However, Elias has never granted 1/2 safeties.  Either a full safety is granted to a single player, or the team gets the safety.
When presented with this fact, Mike Francis agreed that this stat should be dropped.
GSIS WILL NOT USE THIS STAT.

96 Extra Point - Safety If there is a fumble on an extra point attempt, and the loose ball goes into the endzone from impetus provided by the defensive team, and becomes dead in the endzone, the offense is awarded 1 point.
99 2 Point Rush - Safety See Extra Point by Safety.
100 2 Point Pass - Safety See Extra Point by Safety.

A kickoff is "downed" when touched by an offensive player within the 10 yard free zone, and the ball is awarded to the receivers at the sopt of the touch.
