That doesn't mean the Packers don't have a fresh face with that prototypical size.
Last year's seventh-round pick, Lawrence Guy, sustained a concussion during training camp and wound up on season-ending injured reserve. At 6-foot-4 and 304 pounds, he's got what Worthy (6-2, 308), Daniels (6-0, 291) and Hargrove (6-3, 282) lack — the height, length and weight to hold up against blockers.
Guy, a junior entry in the 2011 draft, sustained a concussion at training camp on Aug. 3. He returned to practice five days later and recorded four tackles in the preseason game at Cleveland on Aug. 13, but left practice on Aug. 17 when the concussion symptoms returned.
When finalizing their roster, the Packers planned on giving Guy an injury settlement, meaning they'd pay him for the amount of time he'd be on the sideline — his weekly check of $22,058 multiplied by a negotiated number of weeks. After that period of time, Guy would be free to sign with any team other than Green Bay.
Instead, the Packers were intrigued enough with Guy's potential that they placed him on injured reserve, paying him a split salary of $258,000 that was part of his contract. It wasn't a big financial risk for the Packers, but it was a nod to Guy's potential.
"I appreciated that," Guy said after Wednesday's practice, "but it was a real frustrating period. After a few weeks, everything cleared up but I still had to sit out for the full season. So, that was frustrating because I couldn't contribute to the team."
Guy moved beyond the concussion symptoms sometime in mid-September. While he wasn't able to practice or play, he stayed involved with the team on a daily basis.
"Worked out with the team, studied, went to every meeting," Guy said. "Basically, I did everything with the team but actually step on the field."
Guy's been kicking off months of rust during organized team activities, typically lining up with the No. 2 unit when the Packers run their base 3-4 scheme.
"I like Lawrence," defensive line coach Mike Trgovac said. "He's working hard and doing a lot of good things out there, kind of like when we saw him in training camp before he got the concussion. Lawrence will have a good opportunity to make this team."
While Guy missed week after week after week of practice time to hone his techniques, the season wasn't a lost cause.
"I got a whole year to learn the playbook. That's always a plus," said Guy, who almost lost his eligibility before tackling his dyslexia and attention deficit hyperactivity disorder and becoming an honor student at Arizona State. "I've been training for a whole year just to play this game."
Trgovac agreed that Guy has made strides. On a defensive line that will lose Hargrove and Mike Neal for suspensions and hasn't seen enough out of holdovers Jarius Wynn and C.J. Wilson, Guy has a chance to become a factor.
"I think he got better on studying things, lifting-wise," Trgovac said. "I think he got better on the things he can get better at while not being on the field. Now, he needs to translate all that classroom work and weight room work onto the field. He did a real nice job of being on IR for a rookie, where sometimes those guys don't know how to act. He did a real nice job of taking care of business and doing what needed to be done."
