Pittsburgh ? Let those other teams wear throwback uniforms. The Baltimore Ravens and Pittsburgh Steelers are throwback teams, descendants of the single-wing days of leather helmets, canvas pants and single-platoon football.

Their coaches are named John Harbaugh and Mike Tomlin, but during a different time it’s easy to picture these Ravens and Steelers being coached by George Halas or Curly Lambeau. They hit hard, play with a fury, own a yard-wide mean streak and give an inch as grudgingly as if they were giving up a first down.

In an era of spread formations, five-receiver sets, two-deep zones and a gimmick a minute from some offensive coordinators, the Ravens and Steelers win with defense and toughness. Let other teams try to outfox you — they’ll outhit you and flash a smile while doing so.

Only last week, Steelers quarterback Ben Roethlisberger quick-kicked, of all things. If that’s not something out of a Sammy Baugh playbook, what is?

The Ravens and Steelers are so alike in style, attitude and makeup that it’s difficult to tell one from the other, so perhaps it’s fitting the two rivals will play for the AFC championship tonight. If this isn’t the NFL’s version of a backyard brawl, what is?

May the nastiest team win.

“When you get two bullies going up against each other, it’s about who is the strongest bully,” Steelers linebacker James Farrior said.

The Steelers are playing their third AFC championship game in five seasons, but their first against a division opponent since meeting and beating the Houston Oilers (now the Titans) during the 1978-79 seasons.

Back then, a frustrated Houston coach Bum Phillips threatened to kick down the door and finally beat the Steelers at their own game and win a title. The Oilers couldn’t, and, nearly 30 years later, another division team is trying to beat the Steelers at their own game.

“We are very similar teams,” Ravens All-Pro linebacker Ray Lewis said. “They have a lot of the same type personalities we have. You have ultimate competitors on both sides of the football. I think that’s where it kind of stirs up.”

If the Ravens’ Ed Reed isn’t the NFL’s best safety, Pittsburgh’s Troy Polamalu probably is. If Lewis isn’t the league’s nastiest player, the Steelers’ James Harrison may be. Steelers wide receiver Hines Ward was voted by fans as the most despised visiting player in Baltimore. Ravens quarterback Joe Flacco looks and plays like a slightly younger version of Pittsburgh’s Ben Roethlisberger; Flacco is going for an AFC title barely a year since playing in the Football Championship Subdivision (formerly I-AA) title game at Delaware.

Pittsburgh has the NFL’s best defense statistically in 17 years and Baltimore is second. This is the first time the league’s two top defenses are meeting in a conference championship game since Rams vs. Cowboys during the 1978 season.
