PITTSBURGH - Ben Roethlisberger kept insisting once all the pieces were in place, the Pittsburgh Steelers' offense could hang with anyone.
Looks like it.
Roethlisberger set franchise records with 522 yards passing and six touchdowns and the Pittsburgh Steelers raced by the Indianapolis Colts 51-34 on Sunday.
Roethlisberger's yardage total was the fourth highest in NFL history. He became the first player to go over 500 yards passing twice as the Steelers (5-3) won consecutive games for the first time this season.
Antonio Brown caught 10 passes for 133 yards and two scores. Heath Miller caught seven passes for 112 yards and the clinching TD with 5:14 remaining.
Andrew Luck passed for 400 yards and three touchdowns, but also threw two interceptions. He handed the Steelers a safety when he was called for intentional grounding in the end zone midway through the fourth quarter as the Colts (5-3) saw their five-game winning streak end spectacularly.
The 907 combined passing yards were the second most, trailing only the 971 yards Detroit and Green Bay put up on Jan. 1, 2012.
The Colts gave up 639 total yards and never led, though Luck kept repeatedly threatening to pull off a miracle akin to the 28-point rally he engineered against Kansas City in last year's wild-card playoff.
Indianapolis trailed 35-10 at one point, but had the ball and 95 yards ahead of it trailing 42-34 midway through the fourth quarter. Luck, however, tripped over center Jonotthan Harrison and fell on his backside at the goal line. He flung the ball to the left but there wasn't a receiver anywhere close.
Officials awarded the Steelers a safety when they flagged Luck for intentional grounding to extend Pittsburgh's lead to 44-34.
The Steelers didn't sit on the lead, marching deep into Indianapolis territory yet again. Facing fourth-and-1 at the 11, Roethlisberger faked a handoff and moved to his right, where he found Miller in the back of the end zone for his sixth and final touchdown.
The win gave Roethlisberger 100 in his career in his 150th start, joining Tom Brady, Roger Staubach and Terry Bradshaw as the only quarterbacks in the Super Bowl era to reach that milestone in 150 games.
Roethlisberger claimed ignorance earlier in the week, saying he doesn't keep track. He'll almost certainly remember this one.
The Colts came in fresh off a shutout over Cincinnati; the Bengals managed all of 135 total yards and converted just one third down. The Steelers topped that total by the end of the first quarter.
Rarely pressured, Roethlisberger did whatever he wanted. He completed 18 of his first 20 passes, finding players up and down the depth chart. Markus Wheaton, an afterthought following a dazzling performance in the season opener, caught an 18-yard touchdown pass. Rookie Martavis Bryant, buried on the inactive list for the first six weeks, hauled in a remarkably easy 5-yard score.
Brown didn't even catch a pass until midway through the second quarter, but quickly caught up. His 47-yard touchdown came at the end of a vintage Roethlisberger play as the quarterback evaded pressure, rolled right and found Brown streaking across the field.
The crescendo built even as Luck attempted to counterpunch, with mixed results. William Gay stepped in front of a sideline route and dashed 33 yards for a touchdown as Pittsburgh took a 35-20 lead into the half.
But Luck's sixth straight game of at least 300 yards passing broke the club record he shared with Peyton Manning.
The Steelers flirted with tying the biggest collapse in NFL history before righting themselves -- and their season -- behind their dynamic leader.
