LOS ANGELES -- The booing began early, when three of Case Keenum's first five passes were tipped at the line of scrimmage, and the fans continued throughout, almost every time the Los Angeles Rams' starting quarterback threw so much as an incompletion.

Midway through an eventual 13-10 loss to the Carolina Panthers on Sunday, the fourth consecutive loss for the fading Rams, the boos evolved into demands.

We want Goff! We want Goff! We want Goff!

In the days leading up to this Week 9 matchup, Keenum talked about tuning out all the outside noise with regards to being supplanted by No. 1 overall pick Jared Goff. But on Sunday, in the Rams' first game at Los Angeles Memorial Coliseum in nearly a month, a crowd of 86,109 made that nearly impossible.

"I'm glad the fans care," Keenum later said. "I care, too. I put a lot into this. I put a lot of hours. I put a lot of work into it, and it's something I've worked for my whole life. I'm glad they care because I care, as well, and when we aren't scoring points, and we aren't moving the football, it's frustrating. I can tell they're frustrated. We're frustrated, too."

Keenum, 28, was coming off a four-interception game against the New York Giants in London, after which he had the NFL's lowest Total QBR. Then, on Sunday, he went 27-of-46 with a TD pass and an interception, and he nearly lost a fumble while absorbing one of four sacks. He led a methodical touchdown drive toward the end of the game, taking advantage of underneath routes while the Panthers were in prevent defense, but it came way too late.

Afterward, Rams coach Jeff Fisher sounded like a man who is still not ready to make a change at quarterback.

"I would submit that Case was not the reason we lost this game today," Fisher said. "We just didn't make plays in all three phases. We'll circle the wagons with the coaches and look at the tape, but I'm pleased with the way Case has fought. As I say consistently, repeatedly, week after week, I'm pleased with Jared's progress."

But still not enough to name him the starting quarterback, even though the Rams are now 3-5 and would benefit from providing the future face of their franchise with much-needed game reps.

Keenum has thrown nine touchdowns and 11 interceptions, many of them crucial.

The complexion of the game could've changed if not for a dropped pass from tight end Lance Kendricks: Keenum's pass bounced off Kendricks' chest near the goal line just as he was coming off his route, forcing the Rams to settle for a field goal near the midway point of the fourth quarter.

But there was also a play up the sideline when Keenum overthrew a wide-open Brian Quick.

"That was a touchdown," Quick said.

"It's just tough, man," Quick went on when asked about his quarterback being booed. "He's doing everything he can. You just have to be supportive, make sure that we help him make plays."

The Rams entered the game ranked 30th in the NFL with 307.6 yards per game, and then managed 339. Their defensive line consistently brought pressure on reigning MVP Cam Newton, compiling five sacks, holding the Panthers to 244 yards, and giving the Rams a multitude of chances to pull ahead.

But the offense went nine consecutive drives without a score. And with the passing attack not much of a threat, RB Todd Gurley managed a mere 48 yards on 12 carries, the 15th time in the last 16 games that the star running back has failed to reach 100 yards on the ground.

Asked about Keenum, Gurley said: "He's going to work hard. He prepares every week. A lot of people want to put the blame on him. He's used to that. That's what quarterbacks do. Obviously, the ball is in their hands all the time; obviously, they're going to get the blame. But at the end of the day, we're with him, we support him, and we're going to keep riding with him."

Fisher said he never heard the chants for Goff, which rang loudest from the Coliseum's west end zone. Keenum heard them, and at one point had to quiet the crowd because his offense faced third down.

Every week, it grows more difficult for Fisher to justify keeping Goff on the bench.

"That's not something I think about," Keenum said. "I get ready to play, and that's what I do. I'm getting ready to play the Jets [on Sunday]. We have the 24-hour rule. For me, I have a shower rule. I take a shower. Good or bad, I rinse all the crap off. And I'm looking forward to next week."
