The coin toss for home field for a Ravens/Cincy match up is somewhat unfair. Especially considering there is likely going to be a Bills/Cincy rematch in the divisional round and has high probability of being played in Buffalo. They had their home game taken away and potentially given to the Bills in the playoffs. Surprised they didn't decide to coin toss home field for that match up as well.
Extremely important. A win guarantees at WORST a neutral location for the AFC championship. If Cincy also loses, it has the potential of being a home game.
The important take away here is this:
If the Bills win this weekend, there is NO scenario where they would play at an opposing team's stadium in the AFC championship.
This is also not accurate. If the Bills have a better record than Cincy (Bills win or both Bills and Cincy lose this weekend) then Bills host against Cincy as well.
There are only THREE scenarios where there is a neutral site:
While true they would have uneven games, it essentially doesn't matter. Had the game been played and the Bills lost to Cincinnati, given the scenario Bills beat Patriots and Chiefs lose to Vegas, the Bills would still outrank them.
I'm pretty sure that if the Bills win and the Chiefs lose, the AFC championship game is in Buffalo no matter what because they have the head-to-head against the Chiefs (and a better win-loss record) and would hold a better record than the Bengals.
I actually think it makes a ton of sense after parsing it all out. I'm impressed even. It does the least amount of damage possible. I think the only messy bit is if Baltimore beats Cincinnati and they happen to meet again in the playoffs. Having home-field advantage come down to a coin toss won't feel great. I bet the NFL is praying this situation doesn't happen.
