"You're probably going to have three different groups," McCarthy said. "You're looking at a group in the 10-play area, then a majority of them in the 20-play area, and a select group that will go 30. In the offense, the young guys will probably fall somewhere between that 20- and 30-group."
Like in the team's intra-squad scrimmage on Saturday, rookie linemen Daryn Colledge and Jason Spitz will probably be in at least 20 to 30 plays. Same with third-year pro Scott Wells, who will begin his first season as the starter at center.
To make things more complicated, the offense will be facing San Diego's 3-4 defense, one of the few teams in the league that utilize that style of base defense.
"There's not a lot of teams that run that defense," Wells said. "Their ‘34' is their base package. We see that from a lot of teams in ‘nickel' situations where they have three big down linemen and two off the edge. They run it in their base defense, so it will be interesting. They've had a lot of success with it. We'll see if we can make some holes in that."
McCarthy said that Colin Cole and Ryan Pickett will start the game at defensive tackle between Aaron Kampman and Kabeer Gbaja-Biamila. McCarthy did not name the starting running back, but Samkon Gado and William Henderson are expected to start in the backfield. Running back Ahman Green and linebacker Brady Poppinga, who returned to practice this week, are not expected to play. They are both coming off major injuries from last season.
Injury update Tight end David Martin did not take part in practices today. Martin has an injured left hand. His status for Saturday's game at San Diego is questionable.
Others who did not practice today include: safeties Marquand Manuel (calf) and Atari Bigby (hand), cornerbacks Will Blackmon (foot) and Patrick Dendy (ankle), linebacker Kurt Campbell (hamstring), guard/tackle Will Whitticker (hamstring), and wide receiver Leo Bookman (ankle).
The Packers Thursday signed free agent guard Michael ‘Mookie' Moore today.
Moore, a 6-foot-2, 318-pound player out of Troy State, is a sixth-year veteran who previously has spent time with three organizations. Originally selected by the Washington Redskins in the fourth round of the 2000 NFL Draft, Moore played in five games, including one start, during his rookie season.
He spent the next two seasons with the Denver Broncos before signing with the Atlanta Falcons in 2003. Moore started the season opener in 2004 but was placed on I.R. on Sept. 4 with a shoulder injury. He subsequently was waived on Sept. 9.
In 1999, the Fayette, Ala., native started all 11 games at left tackle at Troy State. He played three seasons at right guard at Alabama before the transfer.
Moore has been assigned No. 57.
