Bush brings experience to the Bears, having appeared in 98 NFL games with 78 starts for the Steelers (2019-22), Seahawks (2023) and Browns (2024-25). Last year, he was the only NFL player to return two interceptions for TDs.
"You go back and you see in our system, how we viewed him coming out of college, he's one of those guys that had a Bears box," Johnson said. "The character matched up with the play style. He's one of those guys. I think he's going to fit in nicely with what we're doing. He's smart. He loves ball. So I feel good that he's going to be a great scheme match."
Bush joins a Bears defense that led the NFL last season with 33 takeaways and 23 interceptions. Players who accounted for 18 of those picks won't return in 2026, but Johnson isn't concerned because he feels that takeaways are not sustainable and believes strongly in defensive backs coach Al Harris.
"He's a phenomenal football coach, obviously, but he's just got a way of teaching these guys to be in a good spot and take the ball away," Johnson said. "That's been his 'MO' since he was coaching DBs in Dallas and that carried on over here. That's why I do have confidence, is that he's still with us.
"Those guys as an entire unit—I'm talking about Richard Smith at linebackers as well—they're very ball conscious, looking to punch that ball out any opportunity that they get. And we're going to continue to make that a focal point for us because, truth be told, that was a big reason for our success last year was our ability to take the ball away."
Johnson feels fortunate that Harris is back with the Bears for a second season.
"It's just a matter of time before he gets that coordinator job," Johnson said. "I know he felt very strongly about coming back in Chicago as well. He had a great time last year. I don't want to speak for him, but he and I had great conversations in terms of his role and his value for us. I think he knows that he's a big reason for our success."
