Even if the Ravens lose their next two matches, they could still win division.
If the Ravens lose to the Bengals but win at Pittsburgh and split the Patriots, Packers and Patriots, then they will be 8-9.
In addition to losing to the Ravens in the season finale, the Steelers would need to drop two against Miami/Detroit/Cleveland.
The Ravens would also need the Bengals to lose one game between Miami/Arizona/Cleveland. The Bengals (4-9), though not eliminated, can still reach eight wins.
