Bears general manager Jerry Angelo insisted that his club did plenty to address the offensive line during the offseason.
"We did everything you could possibly do to that position," Angelo told the team's website. "Nobody did more than the Chicago Bears. We drafted a player in the first round. We brought in a player with a lot of NFL experience who is still in his prime.
"We developed young players who are going into their second and third years, including another high draft pick in Chris Williams. We like our eight linemen. That's not an issue. Injuries happen, and then you have to adjust accordingly."
Angelo was referring to rookie offensive tackle Gabe Carimi, who is sidelined for about a month with a dislocated right kneecap, as well as veteran veteran Chris Spencer, who started at right guard against the New Orleans Saints.
Despite a dreadful second half in which quarterback Jay Cutler was sacked six times, Angelo said the offensive line isn't entirely to blame.
"Everything bad that happened on Sunday wasn't all because of poor offensive line play. Believe me when I tell you that," he said. "It was a collective failure. The defense and special teams share part of that as well. So let's not beat up on the offensive line."
But with Carimi expected out and starting right guard Lance Louis still rehabbing an ankle injury, the Bears need veteran backups to step up and be effective.
Asked about his faith in Spencer and Frank Omiyale, Angelo said, "We have to have faith in them.
"We trained them. They're ours. They've got to step up and get it done. It's that simple. You don't like to play musical chairs at any position, but that's particularly true on the offensive line. You want to keep those five guys the same week-in and week-out.
"They don't have to be the best players, but they have to be players who know each other the best on the field. That's football. So obviously that's going to be our challenge, and I'm confident that the coaches are going to get not only the best out of our players but know exactly what they can and can't do and play accordingly."
Angelo pointed to the most obvious key plays, a 79-yard touchdown pass by the Saints on third and long and the sack-fumble of Cutler, when he took a blind-side hit.
"It was a three-point game at that point and I felt we were playing pretty well in a very hostile environment," Angelo said. "Anytime you play in a dome, the crowd noise definitely can have an adverse effect. After that point, the wheels started to come off.
"The mistakes we made led to five more sacks. It was obvious we didn't handle the adversity of the game well enough."
Angelo said the Bears won't have to wait long to see how well they handle blitzes; the Green Bay Packers' defense uses the same approach.
"So we're going to get a real good test to see how far we have come this week," he said.
The Bears are 1-1, and Angelo said there's no need to "push the panic button."
"We know we're a good football team; we just have to go out there and prove it," he said. "It's that simple."
