A struggling Raiders franchise wasn't accustomed to the drama, not after losing 13 consecutive games to the division-rival Chargers. But something was different when the teams met in the fifth game of the 2010 season.
Jason Campbell was in complete control.
"He brought the team together and said, 'Hey guys, let's take it one play at a time. We're going to win this game,' '' Murphy recalled. "It was a crucial drive and he was just like, 'Man, fellas, let's bring it together. Let's calm down, go out there and make plays.' ''
Campbell, who took over for an injured Bruce Gradkowski that day, guided the Raiders to a 35-27 come-from-behind victory. Throughout the rally, Murphy never saw his quarterback flinch.
"Those are the things you want to see from your quarterback,'' Murphy said. "And you want him to be able to communicate with you efficiently. That was a great characteristic he had.
"And one other thing about Jason is a lot of guys rallied behind him because he's such a competitor. He's a leader. And he's a great quarterback.''
The Bears hope all those things come into play Monday night against the 49ers when Campbell starts his first game since Oct. 16 of last season. His 71st career start comes as a result of Jay Cutler being sidelined with a concussion. Campbell has a career record of 31-39 as a starter with the Redskins and Raiders, but he has won five of his last seven.
"He has played before,'' offensive coordinator Mike Tice said. "Watching him in practice, he brings tremendous poise and leadership.''
Although Campbell has yet to play in the postseason, big games such as that October 2010 showdown with the Chargers helped the former first-round draft pick prepare for this moment.
"I remember that game,'' Campbell said. "It was about unity. Right now, it's about unity. That's the only way we're going to keep winning, is as a team.''
One of the signature plays of that triumph over the Chargers was Campbell's deep throw to Murphy for a 58-yard gain that set up a touchdown. Campbell effortlessly zipped the ball 30-plus yards while Murphy did the rest.
It was nothing Murphy hadn't seen before.
"That's one of his greatest assets, throwing the deep ball,'' Murphy said. "He's precise and has a good spin on it. I'm pretty sure he's going to show you guys what he has with that deep ball.''
Restless Bears fans didn't see enough of it last week after Campbell replaced the injured Cutler in the second half of a 13-6 loss to the Texans. Skeptics wondered why Campbell settled for checkdown throws when Brandon Marshall was matched in one-on-one situations at times.
Campbell chuckled at his first real exposure to criticism in the Chicago market.
"Last week everybody was talking about 'Checkdown, checkdown,' but actually we threw three down the field and completed two,'' Campbell said. "We had a miss on one.
"The rest of the game, their defense understands that a little bit, so they were backing off a little bit and not giving us the deep ball. I had to throw it down. Then if I throw it up and get it intercepted, everybody's like, 'Why didn't you take the checkdown?' "
Campbell completed 11 of 19 passes for 94 yards against the Texans, including a 45-yard hookup with Marshall. The rain and wind also contributed to his decision not to take chances.
"You can't really listen to what (outsiders) say on how you do this or how you do that,'' Campbell said. "I was on the sideline for eight weeks. Any time you come in against a top defense like that, you have to execute. It wasn't easy with those conditions.
"For the most part, we did pretty well. Would we have liked to have done some things differently later in the game? Yes, absolutely. But you just move on from that week, and this week you just keep progressing.''
The right-handed Campbell insisted his throwing hasn't been affected by the broken right collarbone he suffered last October in Oakland, an injury that led to the Raiders going in a different direction with Carson Palmer.
"I thought I got my motion back really about June,'' Campbell said. "When I first got here in Chicago, we started off throwing and I had to miss two weeks of practice because the muscle wasn't there yet to go full speed with a lot of reps.
"I'm good now. The old arm machine is gassed up now.''
Short-time Bear Devin Thomas, who played with Campbell on the Redskins, saw the old Campbell during training camp before Thomas decided to retire.
"Jason, he can just sling it,'' Thomas said. "He has that deep bomb that's so pretty. Even Brandon Marshall talks about how pretty that deep ball is. 'J' just puts it over your shoulder and you can catch it in stride.''
Thomas gained a better appreciation for Campbell each time he stepped in the huddle with the Redskins.
He vividly remembers how Campbell used to address each member of the offense, no matter the situation.
"Pretty much Jason's style is, he caters to the individual,'' Thomas said. "He doesn't treat everybody the same.''
That's not to say Campbell will coddle Marshall and elbow left tackle J'Marcus Webb. But he gets his point across.
Just ask Thomas, who recalled the soft-spoken Campbell berating him after he dropped a ball on a hot route against the Rams one season.
"I was one of the guys he had to treat differently because he had to jump me about being a bonehead sometimes,'' Thomas said. "The thing about Jason is he always kept it real.
"Our relationship was great because we understood each other. He knew when to get on me when I was acting too silly. And I knew when to get on him when I felt like he needed to step it up. So we fed off each other that way.''
Campbell, with just one week of practice as the starter under his belt, is still in the process of figuring out the best way to address his current group of offensive players.
"I'm learning already,'' he said. "There's a certain way you deal with B (Marshall). There's a certain way you deal with (Devin) Hester. There's a certain way you deal with Earl (Bennett) and Alshon (Jeffery). Everybody's personality is different. You can't treat every guy the same because everyone adapts differently.
"But like I said, it's about unity. We have to get to that next level in our offense. A lot of it is a sense of urgency and just playing with a little more emotion. And we have to stop listening to what people are saying, and just start playing.''
Spoken like a true leader.
