Seahawks' line prospects minus Carpenter


The Seattle Seahawks have shuffled linemen through their starting offense without great consequence.

They'll be looking to continue the trend Sunday.

Left guard James Carpenter, listed as questionable on the team's Week 9 injury report Friday, was ruled out Saturday. The team cited a concussion as the reason.

Former starting right guard John Moffitt is expected to start at one of the guard spots. I would expect Moffitt to take over at right guard, with Paul McQuistan moving from that spot to left guard, where he started previously.

Carpenter has been playing his way back into form after missing much of last season following knee surgery. With Carpenter playing more than half the snaps this season, Marshawn Lynch ranks second among NFL players in rushing yards. And with rookie quarterback Russell Wilson showing a good feel for the pocket, the team allowed zero sacks at Detroit in Week 8, the third time in 42 games the Lions have failed to collect one.

Eight players have started on the Seahawks' offensive line this season. Only St. Louis (nine) has started more players on its offensive line in 2012. Teams generally carry nine offensive linemen at a time on their 53-man rosters. Seattle had eight different starters on its line last season.

Russell Okung, McQuistan, Max Unger, J.R. Sweezy, Breno Giacomini, Frank Omiyale, Moffitt and Carpenter have started on the Seahawks' offensive line this season. All but Sweezy, a rookie, and Omiyale, a free-agent addition, started for the team last season. Robert Gallery and Lemuel Jeanpierre also started in 2011.

The chart shows play counts and basic production numbers by line combination this season. The third line listed is the one expected to play against Minnesota on Sunday. "YPA" shows yards per pass attempt. "YPC" shows yards per carry. The chart also shows sack percentage, defined as sacks divided by pass attempts plus sacks.
