Buffalo's run back to the conference title didn't come easily. After leading 21-10 at the half, a furious rally by Lamar Jackson and the Ravens offense cut the lead to just 21-19 going into the final quarter. Baltimore outgained Buffalo by over 100 yards in the third quarter.

Here are five storylines to watch for during the lead up to Bills at Chiefs:

Buffalo answered immediately with an 11-play, 70-yard drive that featured nine running plays, the last a one-yard TD plunge by Ray Davis. The Bills had their own early third down, and Allen hit Khalil Shakir for 34 yards down the seam, and then Allen converted a fourth-and-2 with a seven-yard keeper to keep the march moving.
