In event of a tie record between two teams competing for a playoff slot, the sequence for tiebreakers is:
1. head to head record
2. division record (if teams are in same division)
3. record against common opponents
4. conference record
If teams are still tied after that it goes to points, strength of schedule and finally a pass-punt-and-kick contest between the oldest son or son-in-law of the head coach. (Giants have an edge there, because Snee is our coach's son-in-law.)
If the Giants are tied with the Bears or Packers, the head-to-head result will determine the winner and there is no need to scour the schedule for results of other games. Giants already beat the Bears and have the Packers coming up on the schedule in week 16. Obviously that is an important game for possible wild card tiebreaker with the Packers.
If Giants somehow tie with the Saints, the record against the common opponents is the first tie breaker, since they did not play each other and are not in the same division. Against common opponents of the Saints and Giants, Saints are 5-0 and Giants are 3-1 with a game left against the Vikings. Therefore, Saints will win a tie breaker with Giants.
If Giants tie with the Eagles, the Giants do have an edge. Giants must beat the Eagles in week 15 in order to have a 1-1 head to head record. If the Giants also beat the Redskins, they will be 4-2 in the division and that is the best record the Eagles can attain (assuming Giants beat them next week) so division record will not be the tie breaker. The next tie breaker then becomes record against common opponents and right now the Giants are 6-3 and Eagles are 5-4 against those common opponents. Since all the games remaining for both teams are also against common opponents, if the Eagles and Giants are still tied at the end of the year, the 1 game advantage that the Giants currently have in this category will be maintained. If Giants get lucky and the Eagles lose a game to the Cowboys, their division record will be worse than the Giants and the common opponents do not even come into play.
All together now: "Let's go Cowboys" (clap, clap, clap-clap-clap)
