Basically...
If Seattle, Minnesota and Green Bay each win, and Dallas loses Sunday at New Orleans, all four teams would finish 10-6. In that case, Minnesota would be the NFC North winner, while the Seahawks and Dallas would be the wild cards.
That doesn't seem right does it?[/quote]
That is right if you look at:

except that Seattle has to have the higher strength of victory over Dallas to make it.
I'm not quite sure why Seattle beats out Green Bay because Green Bay beat Seattle in a head to head, unless the tie breaker goes according to "Three or More Clubs" rules below. In that case, the head-to-head doesn't apply for three teams (Seattle, Green Bay, and Dallas) because Green Bay did not beat Dallas OR Seattle did not lose to Dallas during the regular season.

TO BREAK A TIE FOR THE WILD-CARD TEAM
If it is necessary to break ties to determine the two Wild-Card clubs from each conference, the following steps will be taken.
1. If the tied clubs are from the same division, apply division tie breaker.
2. If the tied clubs are from different divisions, apply the following steps.
Two Clubs
1. Head-to-head, if applicable.
2. Best won-lost-tied percentage in games played within the conference.
3. Best won-lost-tied percentage in common games, minimum of four.
4. Strength of victory.
5. Strength of schedule.
6. Best combined ranking among conference teams in points scored and points allowed.
7. Best combined ranking among all teams in points scored and points allowed.
8. Best net points in conference games.
9. Best net points in all games.
10. Best net touchdowns in all games.
11. Coin toss.
Three or More Clubs
(Note: If two clubs remain tied after third or other clubs are eliminated, tie breaker reverts to step 1 of applicable two-club format.)
1. Apply division tie breaker to eliminate all but the highest ranked club in each division prior to proceeding to step 2. The original seeding within a division upon application of the division tie breaker remains the same for all subsequent applications of the procedure that are necessary to identify the two Wild-Card participants.
2. Head-to-head sweep. (Applicable only if one club has defeated each of the others or if one club has lost to each of the others.)
3. Best won-lost-tied percentage in games played within the conference.
4. Best won-lost-tied percentage in common games, minimum of four.
5. Strength of victory.
6. Strength of schedule.
7. Best combined ranking among conference teams in points scored and points allowed.
8. Best combined ranking among all teams in points scored and points allowed.
9. Best net points in conference games.
10. Best net points in all games.
11. Best net touchdowns in all games.
12. Coin toss
