I beg to differ regarding the NFL rules. The Bills and Ravens were the only teams in control of their own destiny going into that week 17 game. Buffalo wins out, they win the conference. Ravens win out, they win their division. Bengals could get the conference only by winning out coupled with a KC loss. So with the Bills v Bengals game cancelled, they put KC at number 1 by virtue of winning % and they awarded the Bengals the Division for the same reason. However...as accommodations for the Bills and Ravens losing the control over their own destinies and losing the conference and division, they put the AFCCG at a neutral field should KC and Buffalo meet, and they decided on a coin flip for a Ravens/Bengals playoff rematch. Winning % was used for seeding and no rules were changed with the exception of those two accommodations.
