Bears cornerbacks struggled for the second straight game Sunday, but coach John Fox isn't blaming any individuals or position groups for the team's 0-2 start.
"Like our whole football team, we need to improve," Fox said Monday. "I don't know if I can isolate the fact that we're 0-2 to one position. I think as a football team we need to execute and play better and we have to coach and prepare them better."
In Sunday's 48-23 loss to the Cardinals, cornerbacks Kyle Fuller and Alan Ball drew pass interference penalties of 42 and 38 yards, respectively, setting up Arizona's first two offensive touchdowns.
Fuller, who also got beat for a Larry Fitzgerald touchdown reception, was replaced by Terrance Mitchell late in the game. But Fox declined to describe the move as a benching.
"I don't know if it was a matter of one particular player sitting down," Fox said. "We actually had [Mitchell] playing for Alan Ball as well. It's just a matter of keeping guys fresh and putting a guy in that's earned the right to do that."
Fuller, a 2014 first-round draft pick, also committed a 34-yard pass interference penalty that set up a Packers touchdown in a season-opening loss to Green Bay.
Asked if Fuller's confidence needs to be repaired in advance of Sunday's game in Seattle, Fox said: "Right now at 0-2 I think guys' mindset—Kyle's or anybody else in that room—is to get better. I think our opponent we play this week is 0-2, so I'm sure they're going through the same type of adjustments and changes as we are."
Fox also spread the blame for the Jay Cutler pass intended for tight end Martellus Bennett that was intercepted by safety Tony Jefferson and returned 26 yards for a TD.
"Probably could have put them in a better position coaching-wise," Fox said. "We didn't execute as well as we need to. I'm not into blaming one guy or a guy. Football's 11 guys doing stuff. We could have coached it better and we could have executed it better."
Fox was asked by a reporter whether it's evident after two games that his job to revive the Bears is tougher than he expected it would be.
"I think all of these jobs are important and they're all tough," he said. "We're not the only team in the league that's 0-2. I don't know if we're the only team in the league that lost yesterday. It is what it is. We need to improve and we're doing everything we can to do that."
