They found it during a five-minute stretch of the second half Sunday.
"It was kind of the focus all week of us kind of cutting it loose, going out there and playing for each other," said Alex Smith, who threw for 297 yards and two scores. "(Reid) always talks about that, letting emotions show, and I thought guys did a good job of that."
It took a while, though.
"Going into halftime, there were so many things we were so close on," Reid said. "The guys settled down, they played - they let their personalities show."
Just about the only downside for Kansas City was the big shot that Jamaal Charles took on a carry near the goal line. He went through concussion testing on the sideline and was cleared to return later in the game, but was eventually pulled with the outcome decided.
"It was a big hit but nothing else," Charles said. "I'm fine."
Derek Carr was 27 of 56 for 222 yards, throwing a TD pass in the final minute. But he also was sacked four times and fumbled a snap that led to a Kansas city touchdown.
The Raiders (2-12) have lost 10 straight on the road, and still have not won back-to-back games since Weeks 7 and 8 of the 2012 season. That includes a pair of duds in the appropriately named Show-Me State - they were routed 52-0 at St. Louis two weeks ago.
"You can't just blame one area," Carr said. "This is a team thing."
"It's to the point where I'm starting to get a feel of it," Thomas said.
Carr fumbled the snap on the next play, Kansas City recovered and Smith hit Kelce from 20 yards for a touchdown. The Chiefs then forced a three-and-out, and Smith's 70-yard throw to Davis a moment later capped their three-TD spurt and gave Kansas City a 31-6 advantage.
NOTES: Chiefs LB Josh Mauga had an oblique strain and CB Sean Smith cramps. Both of them finished the game. ... Kansas City improved to 6-1 when leading at halftime. ... Carr now has 313 completions, becoming the sixth rookie QB to surpass 300 in a season. ... The teams combined to convert 8 of 31 third downs. They also had 21 penalties.
