The numbers game at the defensive end position doesn't seem to be in his favor, but that's not going to stop him from trying to better his technique and potentially flash enough good things to be in the conversation when the final 53-man roster is eventually discussed.
Lewis started behind when he began camp on the physically unable to perform list. That lasted for nearly a week, but since he came off that list Aug. 1, he's been available and on the field.
"I think the biggest thing is he's been available," head coach Jim Schwartz said of his second-year defensive end. "When he came off the PUP he's been available now to practice and play. Last year at this time that wasn't always the case. He was in and out of the lineup and games. I think that it's a little bit different this year."
Lewis, who was drafted in the fourth round last year, played in eight games as a rookie but just one snap on defense.
He played 17 defensive snaps and got one special teams rep in last week's 26-17 victory over the Jets in the preseason opener and was able to make an impact. He recorded two tackles, a sack, a tackle for loss and recovered a fumble. It's the most production he's had in a game in a long time.
Granted, it was the preseason, but it's a good sign for him he's flashing when given the opportunity.
"It's a grind right now and I feel really good helping the team out," Lewis said of his game Friday.
He said he's focused this offseason on adding more moves to his repertoire and trying to become a more versatile pass rusher.
"I felt like last year I got down the middle of a lot of guys," Lewis said. "I'm working real hard to come up with more moves and give the tackle something where he knows I'm not just bull rushing every time. Mix it up a bit."
We'll see if it's enough to catch the coach's eye.
NOT JUST A SPECIAL TEAMS PERFORMER
When the Lions claimed linebacker
Greenwood will have a similarly big role on special teams in Detroit, but he's also proving he can play some linebacker, too. He's currently playing one of the outside spots with the second-team unit, making him one of the team's top six linebackers.
"I feel like you can't just be a special teams guy," Greenwood said. "My friends and family will be like, 'Oh, are you going out for special teams again this year?' I'm like, no, you have to play defense too.
"They have to be able to trust you on defense because injuries happen. It's a long season, people get banged up, and sometimes your number is called and you have to be ready."
Greenwood said his mission so far in training camp has been to prove to coaches he can play defense and he's been doing that.
"I have to prove they can trust me," he said.
The Lions added three to their injured list Monday.
Schwartz didn't address any injury specifically, but said all of then were no more than day-to-day.
The Lions spent a period Monday working on the read-option offense that is becoming a growing trend in the NFL. Fourth-string quarterback
Schwartz and the Lions work every situation in training camp, so this isn't uncommon.
The Lions face quarterback Robert Griffin III and the Redskins, who feature the read-option prominently in their offense, in Week 3.
"It's something that's in the NFL, but it's been in the NFL and college football for an awfully long time," Schwartz said. "Anything that an offense is going to do over the course of the year is going to be important to work on."
HOUSTON HOPING FOR STABILITY
Chris Houston said he's played with "40-something" defensive backs in his three seasons since joining the Lions before the 2010 season.
Louis Delmas has that beat, though. According to Houston, Delmas has played with 54 defensive backs in his first four seasons with the team.
"I don't even remember half of the ones that was in here," Houston said.
Houston is confident that bringing in players like
