Calling it a tie vs. just scrubbing it altogether have the same outcome, as far as playoff seeding. Buffalo, Cincy, and KC all locked up top 3 seeding and can't fall below #3 no matter what. It's just within that top 3 that things get interesting. Both Cincy and Buffalo hold tiebreakers over KC. If they had played the game and Buffalo won, they would be in the #1 spot. If Cincy had won, they would still be a game behind, but could claim the #1 if KC loses next week and Cincy wins. But most of that is moot if they don't replay the game.
If the game is either just scrubbed or dubbed a tie, what it means for seeding is this:
-If KC wins, they are the #1.
-If KC loses and Buffalo wins, Buffalo is the #1, KC is #2, and Cincy is #3 regardless what they do.
-If KC and Buffalo both lose and Cincy wins, KC is #1, Cincy is #2, and Buffalo is #3.
A tie or just having the game "missing" from the schedule has no impact.
So, to summarize: Not playing it at all or calling it a tie has an impact on playoff seeding for the top 3. But either of those options has the same impact.
Those above scenarios also bring me back to some of the negative comments about Goodell/the league initially saying the players should take a break, warm up, and resume the game. I don't have a dog in the fight of whether Goodell is evil incarnate, or something else. But giving him and the league the benefit of the doubt in this situation, since (1) we don't really know all the facts (I was hearing reports this morning that that "you have 5 minutes to warm up and then we will resume play" may not have actually happened, for example), and (2) even if we have all the facts, I don't think we know what the intent was. I could very much see a scenario where it played out something like:
-Goodell/NFL: "Uh...not sure how best to handle this. But both of these teams have a LOT on the line in terms of the playoffs, and it's not fair to all the other players, coaches, and others who have worked so hard this whole season to throw off the playoff seeding by making an executive decision rather than letting it be decided on the field. So I guess let's warm up and resume."
-Buffalo and Cincy coaches: "Yeah, we don't care about that at the moment. We can't go forward right now. Let the chips fall where they may."
-Goodell/NFL: "I'm good with that. Great call."
I could completely respect everything about that scenario without casting stones at anybody.
