Manning threw two touchdown passes to tight end Owen Daniels, and Denver's defense came up with three critical stops late in the fourth quarter as the Broncos beat the New England Patriots 20-18 Sunday to advance to their second Super Bowl in three years.
Manning tipped his hat to his defense for the return trip to the Super Bowl, where the Broncos will try to win their first championship in 16 years and Manning will try to win his second.
"They've been challenging to go against in practice, going back to training camp, but it is special to watch them work and watch them perform on Sunday," Manning said.
Denver coach Gary Kubiak said the win epitomized the style of football the Broncos established throughout the season, winning close games with bruising defensive play and just enough scoring punch from the offense.
"We just kind of held true to what we are," Kubiak said. "We won a lot of games this year just grinding as a football team, playing great defense, and we played tremendous today."
Manning outdueled Patriots quarterback Tom Brady in their fabled rivalry with a huge assist from the defense, led by linebacker Von Miller's 2.5 sacks and interception.
"They're got a great rush," said Brady, whose bid to lead the Patriots to a second consecutive Super Bowl title was derailed. "I think you complement that with good coverage, and it was just tough for us to get in a rhythm and finally score some points there at the end. And for it to come down to a two-point conversion, it's a tough way obviously to end the season."
Trailing by eight at halftime, the Patriots pulled within 17-12 on kicker Stephen Gostkowski's second field goal, a 38-yarder with 10:38 remaining in third quarter.
Denver managed to add a field goal by kicker Brandon McManus, a 31-yarder with 10:02 left to play after Manning slightly overthrew wide receiver Jordan Norwood in the center of end zone on third-and-goal from the 13.
Down by eight and facing fourth-and-1 at the Broncos' 16 with 5:56 left, the Patriots passed up the field goal try. Patriots coach Bill Belichick said he went for it "'cause of the scoring situation in the game."
Brady's pass in the flat to wide receiver Danny Amendola was stopped for a 1-yard loss.
After forcing a Denver punt, the Patriots took over at their own 29 with 4:35 remaining. Again, Brady moved New England downfield, getting a big chunk with a 28-yard pass to tight end Rob Gronkowski.
Facing a fourth-and-6 from Denver's 14-yard line with 2:18 remaining, the Patriots again went for it, and Brady, backpedaling and under duress by Denver's pass rush, threw incomplete to the triple-covered Gronkowski in the end zone.
Denver again was held without a first down, and the Patriots, using timeouts and the two-minute warning, got the ball back at midfield with 1:52 remaining for one last possession.
On fourth-and-10, Brady threaded the needle between two defenders for a 40-yard completion to Gronkowski to set up a first and goal at the 10.
Wide receiver Julian Edelman caught a 6-yard pass between a pair of incompletions before Gronkowski's leaping touchdown grab over cornerback Chris Harris pulled the Patriots within two points with 12 seconds remaining.
Needing a two-point conversion to tie -- Gostkowski missed an extra point in the first quarter, his only miss all season -- cornerback Aqib Talib tipped Brady's conversion pass, and it was intercepted by cornerback Bradley Roby.
Broncos backup safety Shiloh Keo recovered the ensuing onside kick.
"It's football," Gronkowski said. "They have a good defense. It's not like we're going out there and playing some defense that has nobodies on it. They've got great players, and they just made more plays than us when they needed to."
Said Denver linebacker Brandon Marshall after the Broncos' final and decisive stop: "It felt amazing. My favorite word is sensational; it felt sensational."
Manning was sacked three times and completed 17 of 32 attempts for 176 yards.
Brady, who fell to 2-7 all-time at Denver, was 27 of 56 for 310 yards with one score and two interceptions. He was also the team's leading rusher with 13 yards on three carries.
McManus drilled a 52-yard field goal in the final moments of the second quarter, giving Denver a 17-9 halftime lead.
Gostkowski had a 46-yard field goal midway through the second quarter after a Patriots drive stalled when Miller and DeMarcus Ware combined for a third-down sack of Brady.
Earlier, with Miller dropping into coverage instead of rushing the passer, the Broncos linebacker intercepted a Brady pass intended for Gronkowski and returned it 4 yards to the Patriots' 16-yard line. Two plays later, Daniels slipped past linebacker Jamie Collins with a double move, and Manning lofted a pass from 12 yards out that Daniels caught up with in the corner of the end zone.
The Patriots won a replay review to help set up their initial touchdown when it was determined that Manning's pass parallel to the line of scrimmage in the flat to running back Ronnie Hillman, at first ruled incomplete, had traveled backward, allowing linebacker Jonathan Freeny's recovery of the loose ball at the Broncos' 22-yard line to stand.
Running back Brandon Bolden turned a short pass from Brady into a 20-yard gain, and a subsequent personal-foul penalty set up a first-and-goal at the 1. Running back Stephen Jackson scored on the next play, but Gostkowski missed the extra point wide right.
Manning had the Broncos moving on their first possession, guiding them downfield before hitting a wide open Daniels down the middle for a 21-yard touchdown pass.
