After Fokou hurt a knee in Seattle on Oct. 13, his replacement, Colin McCarthy, did the job against San Francisco.
But the Titans came out of the bye with a new player charged with the job.
Strongside linebacker Akeem Ayers called the plays and didn’t leave the field, playing as the middle linebacker in nickel during Tennessee’s 28-21 win against the Rams.
"Coach (Jerry) Gray and coach (Gregg) Williams wanted to try something different," Ayers said. "Last year we had a lot of success in our nickel package when we had me and Zach Brown as the two nickel linebackers late in the season. They just thought it would be good for us after doing a lot of self-scouting in the bye week to come out and do something different."
He played every snap at strongside linebacker in base and at "Mike" in nickel, the most he’s played all season.
I don’t know that his increased presence and role had any great bearing on the team, but it did mark a notable change.
Ayers finished with three tackles and a pass defensed. McCarthy, even playing less, led the team with nine tackles on a day when the Titans played poor run defense, allowing rookie running back Zac Stacy 127 yards on 27 carries, and the Rams 5.0 yards per rush attempt.
Turning to Ayers as the defensive play-caller and with a full-time role might have been just a one-game thing. The Rams are run-first team, and Ayers is better as a run-defender than in coverage.
With Greg Williams added to the defensive staff and the Titans still unsure of how to deploy their second-round pick from 2011, they set out this season to use Ayers as a base linebacker and a nickel defensive end, but he’s not stood out much in either role.
It still needs sorting out, and once Fokou is healthy I expect he’ll be back in the middle as the every-down linebacker and play-caller.
In the meantime, it might have given Ayers a bit of a confidence boost that the team factored him into this plan in a bigger way.
"It was a different position for Akeem to be in," safety George Wilson said. "He did an outstanding job getting us the calls, getting us lined up. Anytime you have a guy who hasn’t played it, you’re going to have a few plays where you get some calls mixed up or we don’t get a call. But that didn’t happen much at all. We were able to get lined up and keep the ball in front of us. That was the goal."
It wasn’t a good defensive day, overall. The Titans did have some good moments, however. St. Louis got the ball twice on turnovers, and Tennessee put on the brakes after the sudden changes, allowing the Rams to convert them into zero points.
And after Jake Locker's second interception looked like it would position the Rams for a clock-milking, game-winning drive, the Titans' defense got the ball back.
Jurrell Casey stripped Kellen Clemens at the Rams’ 17-yard line, Derrick Morgan recovered it at the 19, and Chris Johnson took the next play into the end zone for a 28-21 lead that held up as the final score.
"In sudden-change situations, we won on both sides of the ball," Casey said.
The Titans' defense has been reliable and consistent. But they’ve now allowed touchdowns the past six times opponents have crossed their 20 yard line, they’ve allowed more than 150 rushing yards three games in a row, and they’ve given up a 45 percent third-down conversion rate the past two weeks when it was 27 percent before that.
"For some reason, the last two games that we played, we’ve been slipping," Casey said. "So we’ve got to get back to what we were doing the first couple weeks and turn the game back around."
