When you re-watch that game, it's amazing how the Chiefs messed this up on every level.
They sacked Burrow left and right; and they had at least 4 or 5 more, but tackled miserably and lost him (Burrow is strong and a willing runner, but not all that slick).
The killer was the INT that Mahommes threw to a Dlineman inside the Chief's 30.
The Chief's D also really made a mess of things defensively when the Bengals scored to make it 21-13. The Safety simply went the wrong way. Then in the 2 point conversion, they badly blew coverage to let the guy all alone in the End Zone.
Late, Mahommes was erratic, trying to save every play by running around. The Bengals sometimes dropped 8, but more often dropped 7, with 3 rushing and 1 spy.
