WATCH: Chiefs advance to 4th straight AFC title game with thrilling OT win!

We may have just witnessed the greatest game in NFL postseason history. 

The Kansas City Chiefs are once again headed to the AFC championship game for the 4th consecutive season thanks to an overtime victory over the Buffalo Bills that was nothing short of dramatic, thrilling, and exciting - and that's just for the fans who didn't have a dog in the fight. 

Both teams traded a pair of touchdowns in the first half of the game, setting up an absolutely dramatic second half.

As time went on, both the Chiefs and Bills demonstrated an absolute flair for the dramatic with consecutive drives late in the 4th quarter that appeared to be capped by a would-be knockout blow courtesy of a 64 yard TD run from Kansas City's Tyreek Hill.

But Josh Allen and the Bills announced to the world that they weren't dead yet. Allen once again connected with wideout Gabriel Davis for the 4th time with just seconds remaining to wrestle the lead right back, absolutely shocking the capacity crowd at Arrowhead Stadium.

However, as he's done throughout his career, Patrick Mahomes would lead his team downfield to give them the positioning they needed for the game-tying field goal as time expired.

And in overtime, the Chiefs delivered the dagger to the Bills season courtesy of a Mahomes game-winning pass to Travis Kelce:

The Chiefs will now face the Cincinnati Bengals in the AFC Championship game next week, while the heartbroken Bills once again head home empty-handed.
