What it means: The Chiefs, after leading 13-0 at halftime, survived, but only after a frantic fourth-quarter touchdown drive that was aided by a questionable late-hit penalty against the Titans. Until then, they were miserable in the second half, a collapse so steep that it’s logical to wonder whether the Chiefs were good in the first place. The Chiefs had everything going for them in a lopsided first half but had trouble holding off the Titans, who were playing without injured starting quarterback Jake Locker.
Stock watch: Quarterback Alex Smith had by far his worst game of the season -- throwing a horrible pass in the third quarter that was intercepted. The Titans then went on to score the go-ahead touchdown off the turnover. Smith went on to lead a big fourth-quarter touchdown drive that put the Chiefs ahead for good. Wide receiver Donnie Avery had two big catches of 40-plus yards. Rookie cornerback Marcus Cooper scored a touchdown when he recovered a fumbled punt in the end zone and later had a fourth-quarter interception. Ryan Succop made all of his four field goal attempts, including a 48-yarder with 2:12 to go that put the Chiefs ahead 26-17.
Defensive collapse: The Chiefs allowed the Titans and backup quarterback Ryan Fitzpatrick 153 yards in a dismal third quarter. The Titans climbed to within 13-10 by the end of the period. The Chiefs redeemed themselves with a goal-line stand that featured four plays from the Kansas City 1. They also intercepted Fitzpatrick twice in the fourth quarter.
What’s next: The Chiefs begin a three-game homestand next Sunday when they play the Oakland Raiders. The Raiders have beaten the Chiefs at Arrowhead Stadium in each of the past six seasons.
