Since 2001, the Patriots and Steelers have combined to win nine AFC titles.
Roy Gerela kicked three field goals and Franco Harris rushed for a touchdown to give the Steelers the 16-7 win, the Steelers' 16 points coming unanswered after the Chiefs' Jim Kearney ran an interception back for a touchdown. The next try failed. In fact, it was the home team that scored the game's only touchdowns.
"That's a good thing", the Steelers' left tackle said, "a good thing we have a lot of stuff we can get better at this week". "You're in the playoffs, so you need to throw everything out, whether you played them before or didn't play them before, personnel or whatever it is".
Boswell had already tied the National Football League mark for most field goals in a game with five, a mark held by 10 others.
Still, a general feeling persisted that they know such poor red-zone results next week at New England won't be enough to emerge victorious. He added a team-record 170 yards rushing to the 167 he had in a win over Miami last week.
The Chiefs picked up the game's second touchdown with just 2 minutes, 43 seconds to play in the fourth quarter, when running back Spencer Ware scored on a 1-yard run.
Boswell connected from 22, 38, 36, 45, 43 and 43 yards. The Chiefs mustered only 51 combined yards on their next 14 plays of the first half.
Pittsburgh's answer came on a 52-yard heave to All-Pro Brown, who somehow was covered by Houston.
Boswell has made 50 of 57 field goals since signing with Pittsburgh.
A clean game up until then turned to, well, turnovers, on successive series. Linebacker Bud Dupree played like a man possessed and kept attacking all night. Kicker Cairo Santos ended the quarter with a 48-yard field goal that cut the deficit to 15-10 entering the fourth. Le'Veon Bell topped the 100-yard mark in the first half. They're doing a great job. Come out here and put it through the yellow pipes. "Don't think too much". "And I can't thank the kickoff guys enough for running as hard as they did and being able to tackle as well as they did tonight". Play Under the Total in today's event in Kansas City, Missouri. But because of Boswell's six field goals, the Chiefs had to attempt a two-point conversion.
The stadium fell silent after the incompletion, though the Chiefs had some life left.
The 70,000 or so Chiefs fans here, and the others with their eyes desperately clinging to television sets all over town, probably were the only ones hoping those eyes would soon turn misty and filled with doubt.
The Steelers (13-5) advance to face New England next Sunday night for a spot in the Super Bowl. The Steelers also can not afford to settle for field goals, like they did at Arrowhead.
"With the ref literally taking it out of our hands, that hurts", Chiefs tight end Travis Kelce said. He did finish with five catches for 77 yards. That 18-yard average was well below his 27.4 regular season average.
