JACKSONVILLE, Fla. -- Everybody knows by now that the Jacksonville Jaguars' defense is really good.

It's No. 1 in scoring, total defense, pass defense, sacks, and takeaways. They're also third in interceptions. So it's really, really good. Best in the NFL.

But digging deeper reveals that it has a chance to be historically good, too.

If the Jaguars finish the season atop the NFL in scoring defense, total defense, takeaways and sacks, they will become the first team to accomplish that in the Super Bowl era (1966), per Elias Sports Bureau.

The Pittsburgh Steelers' Steel Curtain defenses didn't do it. Nor the 1985 Chicago Bears or the 2000 Baltimore Ravens, generally regarded as the two best statistical defenses in NFL history. But the Jaguars have a chance, and considering that they'll be playing against Blaine Gabbert, Jacoby Brissett, Tom Savage and C.J. Beathard over the final six games it's a pretty darn good chance.

"We don't go into the season saying I hope we have this, I hope we have that, but I think it's a credit to our players how they come in each and every day," defensive coordinator Todd Wash said. "They work hard. They understand the game plan. They go out and they focus and run it in practice and then they execute it in the game.

"It's really a credit to our players and how well they've been playing."
