Bears defensive coordinator Rod Marinelli knows what it's like to work with an elite defense, given his time in Tampa.
But Marinelli has no problems with his current defenders having lofty goals.
"I think the biggest thing is you set bars. You set a bar, and high," he said. "Guys who are very competitive will try to get to that bar.
"I think the biggest challenge is just day-to-day consistency," Marinelli later said. "They're a highly-talented group. There's no doubt about it. It's down in and down out, playing at an extremely high level."
One player who could help is two-time Pro Bowl safety Brandon Meriweather. But Marinelli, like head coach Lovie Smith, isn't showing his hand on what the expectation is for the veteran.
"It's just kind of week to week, really," Marinelli said. "You get him in and everything is swimming. You're throwing everything [at him]. [He's] a real smart guy. I think he understands everything we're doing. But now it's just doing it; the repetition of doing it, the run fits and all those things."
For now, though, the Bears focus is on the Atlanta Falcons, a club that boasts a dangerous offense.
"They are a team that's got a lot of weapons," Marinelli said. "But I think it really starts with that front. It's a very, very tough front."
