"We had our chances, man, to make plays and get our offense back on the field," Colts safety Antoine Bethea said. "Last game, we were able to do that, but it was a great quarterback, a great offense and a great team we were facing (Saturday)."
The Colts trailed 21-12 at halftime, then cut the deficit to 29-22 on a 35-yard pass to Brazill with 5:01 left in the third. The Patriots dominated the rest of the way.
"We just had to keep our foot on the gas pedal," Blount said, "and make sure that they didn't to us what they did to Kansas City."
Blount's first touchdown came on New England's first offensive play after Alfonzo Dennard's interception. He scored again on the Patriots' second series.
Luck responded with a 38-yard touchdown pass to Brazill. Former Patriot Adam Vinatieri set an NFL record with his 59th post-season extra point, making it 14-7.
Blount's third touchdown came 4:06 into in the second quarter before Vinatieri's 36-yard field goal made it 21-10.
The Colts got a break late in the first half when Danny Aiken's snap sailed over punter Ryan Allen's head, ending up in a safety. The Patriots also got a break that the Colts didn't get a touchdown out of it after Allen failed to concede the safety.
Allen fumbled into the air and Indianapolis' Jeris Pendleton slapped the ball out of the end zone.
"Ryan probably wasn't sure how close they were to him," Belichick said.
Allen hurt his shoulder on the play and placekicker Stephen Gostkowski punted the rest of the game. Brady took over Allen's holding duties.
Indianapolis got the ball on the free kick, but the drive ended with Luck's second interception.
Vinatieri's 21-yard field goal early in the third quarter made it 21-15.
Then the Patriots took a 29-15 lead on Ridley's 3-yard run and his carry for a 2-point conversion.
But Luck came right back with his second touchdown pass to Brazill.
"We didn't accomplish the ultimate goal," Colts running back Donald Brown said, "but there are definitely some positives to look back on."
Brady completed 13 of 25 passes for 198 yards with no touchdowns or interceptions. Luck was 20 for 41 for 331 yards.
Notes: Former NBA star Charles Barkley was in the Patriots' locker room after the game. "I'm a big fan of his," Belichick said. ... A moment of silence was held for 17-year-old Sam Berns of Foxborough, whose battle with a rare and fatal genetic condition that accelerates the aging process inspired Patriots players and was the subject of an HBO documentary "Life According to Sam." He died Friday. He had been invited by Patriots owner Robert Kraft to be the team's honorary captain Saturday.
