DENVER — Booooo!
The Broncos won, again, 35-19 against the bumbling Jaguars.
Not you, and probably not you. But boo on a few of you.
On a sunscreen Sunday, Sports Authority Field witnessed another first: It housed the first fans to boo a team that has won 17 straight regular-season games.
That is unofficial, of course, since booing the home team is one of the few stats left untracked by Elias or ESPN or other football geeks who crunch numbers.
But only five teams in NFL history have won at least 17 straight in the regular season. So it's a safe bet Sunday was a first.
I heard the boos loud and clear, as the Broncos shuffled to the locker room at halftime with a 14-12 lead and a certain level of disinterest playing the winless Jags.
Guess what: the Broncos heard it, too.
"I was kind of surprised. I've never heard boos here," cornerback Chris Harris said afterward. "We're still winning. We're undefeated. It's hard to ever hear us get booed. If an undefeated team gets booed, anyone gets booed."
What were they booing?
The Broncos punting for the first time in October?
I expect it was one of two things: A handful of yahoos who slapped down too much money on the Broncos and an NFL-record point spread, or a reaction to the Broncos taking a knee with 31 seconds left and the ball on their own 20.
Regardless, a boo is a boo.
"You never want to hear booing, especially when you're up," said defensive tackle Malik Jackson, who had two sacks. "I guess they didn't like the situation where Peyton took the knee going into halftime.
"If they want to be the coach, I guess they've got to try out for the job."
This is not to make Mount Elbert out of a molehill. A fanbase that has sold out every home game since 1970 is on the short list for best in the game.
Good luck finding better fans than Broncos fans.
But can we all agree, for a team in the midst of the longest regular-season win streak in franchise history, one boo is too many boos?
Manning is beloved in Colorado. He could run for Denver mayor and he probably would get Michael Hancock's vote.
When No. 18 is introduced on Sundays in Denver, the quarterback is greeted with a king's welcome.
Mile High rocks.
But when the Broncos struggled to a two-point lead over the Jaguars, it rocked for the wrong reasons.
"You usually don't hear that from our fans," Harris said. "I guess we weren't playing up to our standard and to their standard, too."
Quick, what do a BBQ lover in Kansas City, hot milk and Broncos fans have in common?
They're all spoiled.
There is a different scene at Mile High now than 20 years ago. At just about any point during a game, I can scan the crowd and find at least one person checking their Facebook account on a smartphone.
Before the Manning era slides away, here's a friendly tip: Put the phone down and enjoy the show.
Manning suggested these Broncos have been so good, some in the huddle act as if points will pile up simply by slipping on their uniform.
"It's hard. Football's hard. Sometimes you score a lot of points and people take it for granted," Manning said after moving to 19-4 as the Denver quarterback. "I think people even in your own building can take it for granted. It's not easy to win football games.
"I learned long ago to never take winning for granted. Sometimes you have to remind your own players that."
This was part of the deal when the Broncos signed Manning as a free agent. They also signed on for expectations that would be nearly impossible to match.
Whether it's the Ravens Rematch, Manning Bowl or Peyton's Return to Indy, the Broncos seem to highlight the NFL marquee on any given Sunday.
"We get everybody's best," Harris said.
The AFC West is home to the NFL's only unbeatens. Denver and Kansas City are 12-0, combined.
Compare the reaction to their sixth wins on Sunday: Arrowhead Stadium reportedly set a record for crowd noise in an open-air stadium, while Mile High heard boos heading into halftime.
Considering the premature bravado brewing in KC, it might be wise for the Chiefs to act like they've been there before.
It also might be wise to soak in every moment of Manning Mania while you can.
As Manning prepares for a return to Indianapolis next Sunday, I was struck with an unusual thought:
Will Peyton get a friendlier response in a road game than his team got at halftime in a home game?
