"I thought points on the board were important," Crennel said by way of explanation.
Problem was that touchdowns trump field goals.
On the Broncos' final drive of the half, Manning completed five straight passes before finding Tamme on third-and-goal from the Kansas City 7 with 18 seconds left. The touchdown catch, on which the tight end dragged safety Eric Berry into the end zone, gave the Broncos a 7-6 lead and wiped out all the hard work that Kansas City had put in over the first 25 minutes.
Denver's Matt Prater missed his second field goal try of the game early in the third quarter, and Succop's 49-yarder gave Kansas City its first second-half lead of the season.
But once again, a failure to get into the end zone proved fatal.
Manning, who surpassed 3,000 yards passing earlier in the day, rode the legs of Moreno into Chiefs territory, and that's when he lobbed a pass over nickelback Jalil Brown and into the hands of Thomas for the go-ahead, 30-yard touchdown reception late in the third quarter.
"That was a great catch down the sideline against tight coverage," Manning said.
The Chiefs twice had chances to overcome the 14-9 deficit late in the fourth, but they failed to move the ball after taking over at their own 37. After getting it back, Crennel chose to punt on fourth-and-6 at the Broncos 47 after a series of penalties ruined the drive.
It was their last chance to retake the lead.
Denver tacked on a field goal by Prater in the closing seconds, and after Jacksonville held on to beat Tennessee, the Chiefs were left as the league's only one-win team.
"We're frustrated every week. Every time we get a loss, it's frustrating," Charles said. "I don't know when it's going to stop, but hopefully we can did deep down in our souls and find a way to get out of this."
