If we are talking AFC North crown, the main problem is the Bengals are 1-3 in the division where the Ravens are 2-0.
We need the Ravens to drop some of their remaining division games. Even if we split, they would have a better division record which is the first tie breaker.
They still have the Steelers twice and the Browns before us. Not to say they will just sweep all those games, but the Bengals will need some help if we end in a tie.
All that being said, JUST FOCUS ON BEATING KC !!!
Everything else will play itself out.
