According to Y! sports, Sea would win a tie breaker over GB, if Dal lost to NO, since Sea has the better strength of Victory by 2 games. As I understand it, it means that the teams Sea beat have 2 more victories than those the Cowboys beat. In such a senario, if the Cowboys lost, their team cannot get the totals from the Saints, but it would take more than just a single loss by the Steelers to change the Strength of victory. In the final week, the combinations of all the teams Dallas won has to be 3 better than those who lost to Sea. This does get confusing!!
Y!
EDIT: The more I think about it, the more confusing it gets. If there is a tie with GB and Sea.
GB won the head to head.
It is being reported that if Dal lost to the Saints, then Sea would get in via their SOV over the 'Hawks, but neither the Hawks nor the Pack have played the Cowboys. A Cowboy's loss to the Saints does improve the record of the Saints, which loss to Sea.
Then the MNF comment about the PIT/BAL game. Sea played both, lost to the Ravens and beat the Stealers. (I think this is a wash) as if Pit wins they beat a stronger team in Pit but lost to a weaker team in BAL, and vice versus if the Ravens win.
What it comes down to should be the record that the teams GB and Sea played. In either senario, I can't see how PIT/BAL or the DAL/NO effect the GB SEA race.
