Well, the scenarios are definitely interesting! Based on the research I just did ;),
The Chargers are definitely the 2nd seed in the AFC, as for the remaining teams, and who comes next, I would have to say its going to be the Patriots or Cincinnati.
The only reason why I don’t immediately say the Broncos is because of the possibilities that have to occur in order for them to make the playoffs.
The other scenarios are very intricate:
