It's a game of quarters, folks...
 

And the Chiefs seem to only show up in the first two of them. Look at the second half scoring in each game:

vs. San Diego
3rd: KC 0 - SD 7
4th: KC 0 - SD 0

at Cleveland
3rd: KC 3 - CLE 0
4th: KC 3 - CLE 0

vs San Francisco
3rd: KC 14 - SF 0
4th: KC 7 - SF 7

at Indianapolis
3rd: KC 6 - IND 0
4th: KC 0 - IND 10

at Houston
3rd: KC 10 - HOU 7
4th KC 7 - HOU 21

vs Jacksonville
3rd: KC 14 - JAX 7
4th: KC 14 - JAX 0

vs: Buffalo
3rd: KC 0 - BUF 3
4th: KC 3 - BUF 7

at Oakland
3rd: KC 3 - 14
4th: KC 7 - 6

KC has been outscored in the second half in 5 games, coming out with a record of 2-3 in these games. KC has a slight edge in outscoring opponents in the 3rd quarter, but 28 of those points came in blow out wins against San Fran and Jacksonville. KC has been outscored in the fourth by a 41 to 51 margins.

What I'm getting at here is that KC plays horribly in the second half of games, and this hints at a coaching problem one side and a possible lack of mental toughness on the side of the players. Granted, KC is fielding a young roster so this isn't terribly unexpected.

This team will not find success unless they put up 20+ points in the first half, and with this offense that doesn't seem plausible most games. Without looking at stats, the amount of scoring done in the 2nd half by opposing teams was probably carried on the back of the passing game, which KC isn't necessarily good at defending with such a young defensive backfield, especially when the best pass defending rookie is hurt.

Too much effort put into breaking down problems when it consists of one easy answer.
The lack of QB.

YES!

Agreed, but the defense is giving up points. If I had time I'd look up TOP in the second half to see if KC is getting "beat" in this category as well.

Clown shoes.

I think you're onto something there, Mr. Chiefnj2.

It could well be that the big, red nose of conditioning is preventing the oral sex of offensive production because it keeps bonking into the pelvic bone of 3 and outs.

Raiders definitely owned the 2nd half yesterday.
