They were OK on Sunday even without Charles Tillman, who left the game in the second quarter with a leg injury.
"When you want to set the tone on the defensive side, you want to do it with a big hit, let them know you are there," Hayden said.
We know the Bears defense is there now.
There had been some concerns before Sunday afternoon that for the first time since face-masks the Bears offense would have to carry the defense.
Could you imagine?
That would have given Otis Wilson something to woof about.
Steve McMichael might be pointing out he also was a Packer and a Patriot.
Ed O'Bradovich would be wearing a disguise to work.
But none of that will be necessary now.
They asked Colts rookie quarterback Andrew Luck about the speed of the game afterward, and he said it had sped up against players like Briggs, Peppers, Melton and Urlacher.
"There's a lot of speed out there and they're a fast (defense)," he said.
You can play fast. Or you can play old. But you can't play both.
The Bears defense played fast. But the defenders didn't mind slowing down to watch their brothers on offense.
"I love watching our offense," Conte said. "It's great to have an offense that can score points and feel like every time they're on the field they are going to score. I have no problem with them being great. It's great motivation for us."
The old dogs even showed a new trick. The defensive linemen didn't just line up in their spots and rush as usual. They moved around before the snap and came at Luck from different positions.
"Hopefully that gives our opposition some things to think about when they are lining up," Idonije said. "It's not going to be just the same look. Some of those things worked really well today."
The opposition definitely has some things to think about. As do any of us who thought this defense might be showing signs of vulnerability.
