If that happens, and Cinci goes 2-1 (8-4 in conf) and SD goes 1-2 and (beats Wash), all 3 teams will be 11-5 AND 8-4 in conf
If that happens....
NFL Tie-Breaking Procedures
Going off of this: "To determine home-field priority among division titlists, apply Wild-Card tie breakers."
Wild Card Tie-breakers: 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.
