IDK, nothing is sealed yet. Every team in contention for each division in the AFC still have some potential losses by good to very good teams.
The Texans still have the Colts twice, the Pats, and the Vikes. Both the Colts and Vikes are still in contention for Wild Cards and could be tough outs for a team currently struggling to beat bad teams. If the Texans continue to play like they have the last month, I can see two or three more losses before the end of the season.
The Ravens' final schedule is very tough. They have the Broncos, Steelers (won't be all that tough if Roethlisberger isn't back), Redskins, Giants, and Bengals. All those teams are either definitely playoff bound or in contention.
The Broncos still have the Ravens and Bucs who are both still in playoff contention.
The Pats still have Miami twice, Houston, and the 49ers. All are in playoff contention and Houston and the 49ers have two of the best records in the NFL.
The Pats basically have to win out or only lose one more game to even dream of a bye, but all the top teams in the AFC have potential losses on their horizon. I wouldn't be surprised if the Pats and Broncos have the first round bye when everything is said and done.
