On Sunday, he showed exactly why Kansas City was after him.
It allowed Manning to break a tie with his boss and Broncos vice president John Elway with his 149th win as a starting quarterback, trailing only Brett Favre (186) for most in NFL history.
Naturally, Manning was quick to pass the praise to someone else.
"I've got to tip my hat to Knowshon Moreno," Manning said. "He stepped up today and did a heck of a job. Really an impressive effort by him."
Quinn was 13-of-25 passing for 126 yards and an interception.
Kansas City actually established an early lead for the third consecutive game on Succop's first-quarter field goal, and seemed to be outplaying Denver (8-3) the entire first half.
They had a chance to go ahead 10-0 when they faced fourth-and-2 at the Denver 4, but Chiefs coach Romeo Crennel elected to kick another field goal against a team that had scored at least 30 points in five consecutive games, drawing a chorus of boos from the crowd.
"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 consecutive 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.
"That was a great catch down the sideline against tight coverage," Manning said.
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."
