That reaction was shared by several members of the struggling squad.
Flacco admitted he feels somewhat responsible for Cameron losing his job.
"No doubt," Flacco told reporters. "I think as an offense, we have to look at ourselves and see what we can do to be better. Obviously, we weren't good enough."
The Ravens' offense ranks 18th in the NFL in yards and ninth in points. It hasn't ranked above 13th in the league in five years under Cameron.
But Flacco and Cameron have been attached since the quarterback was drafted by Baltimore. Flacco said he did have an opportunity to say goodbye to the only offensive coordinator he has known at the pro level.
"I talked to him. And listen, Cam has done so much for my career. He brought me here and trusted to bring me here, first of all," Flacco told reporters. "He's just helped me every year I've been here, so I'll never forget that. He's been great for me."
Running back Ray Rice spoke extensively about his reaction to the news.
"My first reaction is to sit back and reflect. Needess to say, I have tremendous respect for Cam Cameron and what he's done for me over my career. Two Pro Bowls ... It's many countless things," Rice told reporters. "I look back on the good. Cam is a genuinely a good guy. Nobody goes out there and says, 'I'm going to mess up this kind of situation.' I did send him a text and wished him well, thanked him for everything that he has done for my career. For his family, wished them much success. He's a great coach.
"I know the pressure to win in this business. It's always tough to see a guy go while you're still going. Needless to say, he was well-respected by the players. The amount of games we won over the last couple of years is amazing. He had a great run. You look back on the good. Everything was a growing experience. We are still a growing offense."
As for the potential affect of the move, Rice said he believes it can spark the Ravens.
"This is something that I think it's a wake-up call for everybody," Rice told reporters. "You never know when your day is going to be called. It's a wake-up call for everybody around the building. If you can let go an offensive coordinator in the middle of your season ... nobody here wants that to happen, but it's a wake-up call for everybody around the building. The expectation is to win around here. We want to win. There's a reason why you put the Lombardi Trophy (banner) in the indoor facility.
"It's the only thing you can see; it's the biggest sign in here. The expectation is to win around here. We've been to the playoffs. We've been to The Dance. Getting to The Dance is sometimes not enough around here anymore. We like to keep dancing - dance all the way to the Super Bowl. That's the challenge. That's a very hard challenge."
The Ravens move on with quarterbacks coach Jim Caldwell as offensive coordinator.
Flacco seems to be a fan of Caldwell in his first season working with the former Indianapolis Colts head coach.
"Jim's great. He's a great person and he's a great coach," Flacco said. "The little time that he's been here, we've had a great working relationship.
"The biggest thing that we've talked about is just coming together as an offense and everybody helping, and giving their input, because we're going to need it. It's a quick change, it's late in the year, and it's going to require all of us to be focused and work hard and come into this thing and work together."
