Foxborough, Mass. ? Tom Brady was almost perfect. The Patriots still are.

Their poised and prolific quarterback knocked another mark out of the books in their record-breaking season, completing all but two of his 28 passes to lead New England to its second straight AFC championship game with a 31-20 victory over the Jacksonville Jaguars on Saturday night.

The Patriots pulled away in the second half to improve to 17-0, matching the 1972 Miami Dolphins, the only team to go unbeaten from the first game of the season through the Super Bowl.

Two more victories and the Patriots will join them – much to the chagrin of some of those Dolphins.

Just one more win next Sunday at Gillette Stadium will put the Patriots back in the Super Bowl for the first time in three years after three championships in the previous four years. They’ll face the winner of today’s game between San Diego and Indianapolis, which beat New England in last year’s AFC title game.

“The thing about it now is that none of it matters.” Brady said. “For 17 games, it all comes down to this, and we were here last year. I hope we perform better.”

Brady completed 92.9 percent of his passes, breaking Phil Simms record of 88 percent (22-of-25) set in the Super Bowl after the 1986 season in which he led the New York Giants to a 39-20 win over the Denver Broncos. And Brady did it mostly without Randy Moss, who had only one catch against double- and triple-coverage.

“They went back to the old way of covering me,” Moss said. “We win as a team. I’ve never been a greedy guy. I’m not going to start now.”

Brady hit all the other receivers – throwing for three touchdowns and 262 yards.

“When they’re open like that, it’s my job to hit them,” he said. “They were open every time, so it’s easy to play quarterback.”

While Jacksonville’s defense struggled to stop Brady and crew, New England’s defense had no such problems against the Jaguars’ one-two rushing punch of Fred Taylor and Maurice Jones-Drew. The league’s second-most productive duo during the regular season combined for just 66 yards.

It was the Patriots who dominated on the ground as Laurence Maroney rushed for 122 yards, including a one-yard touchdown.

Add Brady’s on-target passing to these regular-season records – 50 touchdown passes by Brady, 23 scoring catches by Moss and 589 points by the team – and Jacksonville (12-6) became just another team that couldn’t stop the Patriots.

And they’re not done yet.

“Brady’s been great all year,” Jaguars coach Jack Del Rio said. “He’s as good as they come.”

Brady completed his first 16 passes before the next one went off the hands of Benjamin Watson, who caught two others for touchdowns.

The next nine passes found their targets before one went right through Wes Welker’s hands with 6:46 left in the game.

“I thought he managed the team well,” coach Bill Belichick said. “Of course, he threw the ball well.”

One throw the Patriots didn’t make may have helped the Jaguars take a 7-0 lead. David Garrard completed an eight-yard touchdown pass to Matt Jones on their first possession. He threw as he was going down while in the grasp of Mike Vrabel, and his knee might have touched the turf before he released the pass.

Belichick pulled the red challenge flag from his sock, but held on to it.

“It was just too late by the time we got a look at it,” he said.

Brady tied it on the Patriots’ first possession with a three-yard scoring pass to Watson.

New England capitalized on Garrard’s fumble on Jacksonville’s second possession when he was hit by Ty Warren and Vrabel recovered at the Jaguars 29. On the first play of the second quarter, Maroney ran in from the 1.

But Garrard, in just his second playoff game, kept matching the success of Brady, a two-time Super Bowl MVP. He completed 22 of 33 passes for 278 yards and two touchdowns.
