It does, it also hands KC control of the #1 seed. Which then impacts the WC race because KC could wrap it up on Saturday.
It's not fair but I could see the Bengals and Bills players agreeing to it if the league tries to get them to play within the next 2-3 days and refuses to add a week 19.
From a technical perspective, I’m not sure Goodell has the authority to declare a tie, even with the consent of the teams. I’m not sure if the Competition Committee could pass a rule change broadening Goodell’s authority with retroactive effect, either. Anyways, this is fundamentally a political issue for the league. They’ll need to get any teams affected by a declared tie or cancellation to not fight it publicly.
From Rule 17:
(…)
ARTICLE 4. EMERGENCY SITUATIONS. The NFL affirms the position that in most circumstances all regular-season and postseason games should be played to their conclusion. If, in the opinion of appropriate League authorities, it is impossible to begin or continue a game due to an emergency, or a game is deemed to be imminently threatened by any such emergency (e.g., severely inclement weather, lightning, flooding, power failure), the following procedures (Articles 5 through 11) will serve as guidelines for the Commissioner and/or the duly appointed representatives.
The Commissioner has the authority to review the circumstances of each emergency and to adjust the following procedures in whatever manner the Commissioner deems appropriate. If, in the Commissioner’s opinion, it is reasonable to project that the resumption of an interrupted game would not change its ultimate result or adversely affect any other inter-team competitive issue, the Commissioner is empowered to terminate the game.
‘ARTICLE 5. LEAGUE AUTHORITY. The League employees vested with the authority to define emergencies under these procedures are the Commissioner, designated representatives from the League office staff, and the game Referee. In those instances where neither the Commissioner nor the designated representative is in attendance at a game, the Referee will have sole authority; provided, however, that if the Referee delays the beginning of or interrupts a game for a significant period of time due to an emergency, the Referee must make every effort to contact the Commissioner or the Commissioner’s designated representative for consultation. In all cases of significant delay, the League authorities will consult with the management of the participating clubs and will attempt to obtain appropriate information from outside sources, if applicable (e.g., weather bureau, police).
ARTICLE 6. LATER DATE. If, because of an emergency, a regular-season or postseason game is not started at its scheduled time and cannot be played at any later time that same day, the game nevertheless must be played on a subsequent date to be determined by the Commissioner.
ARTICLE 7. PRE-GAME THREAT. If there is deemed to be a threat of an emergency that may occur during the playing of a game (e.g., an incoming tropical storm), the starting time of such game will not be moved to an earlier time unless there is clearly sufficient time to make an orderly change.
ARTICLE 8. INTERRUPTED GAME. If, under emergency circumstances, an interrupted regular-season or post-season game cannot be completed on the same day, such game will be rescheduled by the Commissioner and resumed at that point.
ARTICLE 9. ALTERNATE DATES, SITES. In instances under these emergency procedures which require the Commissioner to reschedule a regular-season game, the Commissioner will make every effort to set the game for no later than two days after its originally scheduled date, and will attempt to schedule the game at its original site. If unable to do so, the Commissioner will schedule it at the nearest available facility. If it is impossible to schedule the game within two days after its original date, the Commissioner will be guided by the Emergencies and Unfair Acts provisions in the Policy Manual for Member Clubs: Game Operations.
ARTICLE 10. POSTSEASON INTERRUPTION. If an emergency interrupts a postseason game and such game cannot be resumed on that same date, the Commissioner will make every effort to arrange for its completion as soon as possible. If unable to schedule the game at the same site, the Commissioner will select an appropriate alternate site. The Commissioner will terminate the game short of completion only, if in the Commissioner’s judgment, the continuation of the game would not be normally expected to alter the ultimate result.
ARTICLE 11. GAME RESUMPTION. In all instances where a game is resumed after interruption, either on the same date or a subsequent date, the resumption will begin at the point at which the game was interrupted. At the time of interruption, the Referee will call timeout and will make a record of the following: the team possessing the ball, direction in which its offense was headed, position of the ball on the field, down, distance, period, time remaining in the period, and any other pertinent information required for an efficient and equitable resumption of play.’
