The first Tie break for a division tie is head-to-head and of course San Diego and Denver are tied after that. The next tie breaker is record against division teams San Diego is 5-1 and Denver is 3-1 with Kansas City and Oakland left. So obviously if Denver loses to either one of those teams they lose the tie break. So this post is assuming Denver beats both Kansas City and Oakland.
If Denver wins all remaining games and finishes in a 12-4 tie with San Diego it will mean that San Diego lost 1 game. If that 1 loss is to Tennessee then San Diego wins the division based on a better record between common opponents San Diego10-2 Denver 9-3
If San Diego losses to Dallas or Washington then both teams would be tied vs common opponents and we would go to Conference record were both teams would be 9-3 which then would send things to the 5th tie breaker Strength of victories. In this case we would note which teams the other team has not beaten. Which would be New England, Indianapolis, and possibly Dallas for Denver and there records compared to Tennessee, Miami, and possibly Washington. Clearly Denver's opponent would have a better record and Denver would get the division.
Lets say that one loss of San Diego's was to Cincinnati then Common Opponents would be tied. Denver would get the Division based on Conference record 9-3 to 8-4.
I was going to this for ties at 11-5 and 10-6 but that would have even more variables and I think you all would get bored with it. Besides I don't have the energy for that. At any rate I think everyone has enough of an idea to apply the tie breakers to the additional scenerios. I think Denver has an excellent chance to win a tie breaker if that what this division ends up in. What do you think?
