You can guess what happened.
Yep, backup Derrick Blaylock rushed for 186 yards, Trent Green threw for 311, the Chiefs ran up 497 yards and held the ball for nearly 36 minutes and still found a way to lose, 27-20, to the team with the NFL's worst defense.
They did so because the league's No. 1 offense (in total yards) committed two turnovers in the red zone -- the last a Trent Green interception from the Saints 17 with 1:16 remaining -- and two others in the New Orleans end.
They did so because Kansas City's Career Day Defense gave up a season-high 127 yards rushing on a mere 16 carries by Deuce McAllister and three completions of more than 40 yards to Joe Horn -- the biggest a 42-yard split-the-safeties grab for the winning touchdown with 5:28 remaining.
They did so by making 10 of their season-high 12 penalties in the first half when they trailed 14-13 at halftime of a game they probably should have led 21-0 in the early going.
They did so because they got only a field goal on six snaps from the New Orleans 5. They did so because Johnnie Morton fumbled a long reception at the Saints 5, then later fell down on a deep route that was easily intercepted. They did so because Green tried to force a crunch-time, scoring-zone throw rather than take a third-down sack in the final two minutes. And did we mention those drive-sustaining penalties they made on defense?
"It's almost like we keep finding ways to lose," lamented Green, who now has failed at three drives for either a game-tying field goal or touchdown in the final minutes of consecutive losses of winnable games at Tampa Bay and New Orleans.
Added Dante Hall: "It's one thing when you just suck and can't beat anyone. It's another when you're good enough to beat anyone but you end up beating yourself.
"People want to say we're a bad and awful team," Hall added. "We're not a bad and awful team. We're just making bad and awful mistakes."
Yeah, that too.
