Insane win-probability graphic from Bills-Chiefs game goes viral

The end of regulation between the Kansas City Chiefs and Buffalo Bills on Sunday was absolutely ludicrous. If you want an idea of just how chaotic it really was, look no further than the win-probability calculator for the game.

The Chiefs led for most of the second half of the divisional playoff contest and took a 26-21 lead late into the fourth quarter. But the Bills responded with a Josh Allen touchdown strike to Gabriel Davis and subsequent two-point conversion to take a 29-26 lead. The Chiefs then hit back with a touchdown of their own on a 64-yard catch and run by Tyreek Hill from Patrick Mahomes to go back up 33-29.

Not to be outdone, Allen countered with another touchdown pass to Davis with just 13 seconds left to retake the lead at 36-33. But 13 seconds was all Mahomes and the Chiefs needed. Mahomes got the Chiefs into field-goal range with a couple of big pass plays, and Harrison Butker hit a 49-yard field goal to send the game into overtime at 36 all.

The wild seesaw battle produced an ESPN win-probability graphic that looked like a seismometer measuring an earthquake. Take a look.
