ALAMEDA – Clelin Ferrell stepped on the scale Thursday morning, looked down at the number below and flashed his signature smile.

The readout was the reason why: 266 pounds.

The Raiders defensive lineman finally was back to his playing weight.

The experience was a lot different after coming back from a week in the United Kingdom dealing with concussion-like symptoms and a stomach flu that made it, shall we say, hard to keep things down.

“When we got back from London, I stepped on a scale and I was 250,” Ferrell said. “I couldn’t believe it, but it wasn’t just the weight. I felt bad and I felt weak.”

Ferrell hasn’t been that light in six years. Getting there wasn’t pretty. Getting back to his playing size and strength took some time, but Ferrell’s return to health was well-timed.

It came accompanied by an on-field epiphany. Or, as defensive coordinator Paul Guenther put it, “the light came on.”

“You can just tell with the look in a guys’ eyes,” Guenther said. “You know when he starts making plays, you can start saying, ‘Hey I’m starting to figure this out.’ It’s the look in the guys’ eyes and the way he’s handling himself.”

Something clicked during a Week 9 victory over Detroit, where he had three huge run stops and three quarterback pressures, including one that flustered Matt Stafford on the final play of the Lions' failed comeback attempt.

Guenther approached the No. 4 overall pick after that win and could tell right away that something was different. He was right, and Ferrell knew exactly why.

“Facing the Detroit Lions was the first game where I felt comfortable with everything that I was asked to do,” Ferrell said. “Before, it was like, ‘I’m comfortable with this and this, not so sure about this over here.’

“I have been asked to do a lot of stuff. The whole practice week leading up to it, I felt really good with everything. I felt comfortable and that I could just go out there and play and put my own flavor on it and freestyle a bit. I really understood my responsibilities and I felt really good.”

That wasn’t a one-off. Ferrell built upon that with a breakout game last week against the LA Chargers, totaling 2.5 sacks, two other quarterback pressures, a batted pass and six run stops. Ferrell paced an all-out assault on quarterback Philip Rivers, where the pass rush made a significant impact on a dramatic win.

Ferrell didn’t say much after the game, answering one question before leaving the Raiders' locker room. Many said the Clemson product needed a game like that, especially after absorbing fan criticism for not producing enough, especially relative to his lofty draft slot.

Ferrell doesn’t care much about numbers. He’s concerned with two things: wins and personal impact. He admitted, in that instance, it was nice to have a good game in ways all can understand.

“When you’re chasing stats, you’re not focusing on what you need to do to win,” Ferrell said. “It’s always good to shut people up a little bit. People can get on your nerves. Not that it’s getting to me, but you hate hearing nonsense, especially when they aren’t that informed. I don’t blame people for that. It is what it is, and I’ve been through this before when I was in college. I’ve always had the spotlight on me. It just comes with the game.”

Lights were always bright at Clemson. That comes with the territory as a perennial championship contender.

The same goes for top-five NFL draft picks, so the scrutiny was sky-high even over such an early portion of his career.

But not from inside the Raiders organization.

The Silver and Black were asking Ferrell to do a ton. He stepped right in as a three-down player, asked to play inside far more than he did in college. That was an adjustment, one he insists he’s comfortable with despite a productive athletic career playing off the edge. He has played several techniques to service defensive line needs, doing some dirty work that doesn’t show up in the stat sheet.

“He does a lot more than just rush the passer,” head coach Jon Gruden said after beating the Chargers. “He made some great plays against the run. It was a signature game for him obviously, but it’s great for him to get some sacks. Maybe some of the people who are counting sacks out there will acknowledge this.”

Ferrell isn’t counting them. He’ll evaluate himself through a different lens.

“The biggest thing for me is wins and losses and whether I feel like I played well,” Ferrell said. “I don’t really care about stats, you know what I mean? Numbers are good but seeing the success I had and the big role I played in two huge wins was really, really good.”

Continuing this positive trend is the next step, one that renewed health and increased comfort within his role will help achieve.

“He needs to keep it going. Clelin’s coming off his best game,” Guenther said. “I really think the light came on for him in the second half of the Detroit game. Walking off the field with him I was like, ‘I think the light just came on for you. Really.’ And then he went out against the Chargers and played really well, so hopefully he can keep playing at a high level.”
