Updated: NFC West roided-out rosters

The 26-column NFC West team rosters featuring more than 1,800 current and former players have been updated to include new information from 2010.

We can now see which players were on Week 17 rosters as backups, starters or as players on injured reserve. This info lets us sum up roster turnover for teams in the division.

In a few cases, backups from Week 17 last season were actually starters resting injuries. That was the case for the San Francisco 49ers' Patrick Willis. Overall, though, the numbers paint an accurate general picture.

The Seahawks have undergone the highest turnover from last season. Twenty-six players on their current 53-man roster were not on the 53-man roster or injured reserve in Week 17 last season. They have a division-low 11 starters from Week 17 on their roster at present. The St. Louis Rams have a division-high 18.

Unfortunately for Seattle, a couple of their top new players likely will not help them Sunday. The team expects receiver Sidney Rice (shoulder) and left guard Robert Gallery (knee) to miss the regular-season opener at San Francisco.

With Gallery out, the Seahawks have only one projected starter age 30 or older: Marcus Trufant. The Rams have eight, the Arizona Cardinals have six and the 49ers have five if Madieu Williams replaces the injured Dashon Goldson at safety, as expected. With Goldson listed among backups, the 49ers have the third-youngest offensive and defensive non-starters in the league, while those for Arizona and St. Louis rank among the four oldest.

We'll call those older backups "veteran depth" if the Rams and Cardinals enjoy strong seasons.

The second chart, updated to reflect Seattle's move to sign Anthony Hargove at Landon Cohen's expense, shows NFC West roster counts based on where players went to college. Conference affiliations are current, not necessarily as they were when players were in college.

The Seahawks remain heavy on players from the West, specifically the Pac-12. The Cardinals take pride in developing players from the Division I-AA (FCS) ranks, including receiver Andre Roberts, quarterback John Skelton and tackle Brandon Keith.
