In terms of historical Super Bowl success, Pennsylvania's NFL teams sit on opposite ends of the spectrum.

But the Pittsburgh Steelers' six titles and the Philadelphia Eagles' five decades of championship futility are in the past. If you're focused on the 2017 NFL season, you've probably noticed something: Both teams are playing well enough to fuel realistic hopes of the first all-Keystone State Super Bowl in league history.

The Steelers (9-2) earned a thrilling win over the Packers on Sunday night to keep pace with the Patriots atop the AFC standings, while the Eagles (10-1) own the NFC's best record after routing the Bears for their ninth consecutive victory.

Each squad has better than a 99 percent chance to make the postseason, according to FiveThirtyEight's NFL predictor algorithm. And their odds of meeting in Super Bowl 52 at Minneapolis' U.S. Bank Stadium in February? Well, those are a bit more conducive for debate.

Gambling experts give the Eagles 2 to 1 odds to win the NFC championship, the best of any team in the conference, according to VegasInsider.com. The same site tabs the Steelers' odds of making the Super Bowl at 5 to 2, second in the AFC behind the Patriots. (Here's how this numbers work: For every $2 a bettor puts down on the Steelers to win the AFC, they get $5 in winnings if that comes to fruition).

If we multiply the Eagles' 2 to 1 odds by the Steelers' 5 to 2 mark, we get 10 to 2 odds that the teams will meet in the Super Bowl. That equates to out to a 20 percent chance, in gambling terms.

The New York Times' NFL Playoff Simulator offers more analysis. The Times' algorithm gives the Eagles a 67 percent chance of earning the top seed in the NFC, while the Steelers have a 44 percent shot at getting home-field advantage through the AFC playoffs, which means both teams could enter the playoffs as favorites to reach the Super Bowl.

FiveThirtyEight's simulator gives the Eagles (18 percent) the second-best chance of capturing the title and tabs the Steelers (14 percent) as the third-most likely Super Bowl winner. Only the defending championship Patriots (27 percent) have a better shot at taking home the Lombardi Trophy than the Pennsylvania teams, according to FiveThirtyEight's numbers.

In any case, an Eagles-Steelers Super Bowl would be a first, though there have been a few near-misses.

The Eagles made their first trip to the big game in 1981 -- and lost to the Raiders -- one year after the Steelers captured their second consecutive Super Bowl championship with a win over the Rams. And the only other time Philadelphia played in the Super Bowl was a 2005 loss to the Patriots, one season before the Steelers beat the Seahawks for their fifth championship.

With both teams in leading their respective conferences this year, the Eagles and Steelers could finally cross paths in the postseason. But how likely is an all-Pennsylvania Super Bowl?
