The Seattle Seahawks have reveled in their roster activity since Pete Carroll took over as coach following the 2009 season.
"Carroll and general manager John Schneider made 284 roster transactions in 2010 and are continuing to shape a roster with bigger, faster, talented young players this season," the team's weekly in-season news release says. "Of the 53 players currently on the active roster for this week's game, only 10 were with the team in 2009."
NFL Turnover by Division
This matches the information I've tracked for every NFL team. The Seahawks are not the only ones to have made a nearly complete makeover since 2009. Every NFC West team ranks among the NFL's top 10 in most new players since the final week of the 2009 regular season.
A few numbers within the numbers:
Five players who started for Seattle in Week 17 of the 2009 season remain with the team. Cleveland (six), Buffalo (seven), Carolina (eight), Washington (eight) and New Orleans (eight) are the only other teams with fewer than 10. The Saints were an exception because they rested some starters in that final game.
Seattle (five), Detroit (five), St. Louis (five) and Baltimore (six) have the fewest backups from 2009 Week 17 remaining on their rosters. Philadelphia (seven) and Washington (seven) were not far behind.
The most consistently strong teams over the past few years naturally rank near the bottom in turnover. They've had good players, for the most part, and kept a lot of them.
The chart below breaks down the new players by team. By new players, I mean those who weren't on the 53-man roster or injured reserve in Week 17 of the 2009 season. These numbers are through Monday, plus a move or two from Tuesday, including David Garrard's release.
If NFC West teams are improving, they'll retain their coaches and turnover numbers should decline over time.
