The Seahawks expect to get younger under new coach Pete Carroll and new general manager John Schneider.
The roster database I maintain allows for quick age calculations across multiple criteria. The chart shows average ages for each team's 53-man roster and any players on injured reserve. I excluded players signed to future contracts because they have not yet joined active rosters, most of them are young and some teams are only beginning to add these players with an eye toward 80-man limits.
Schneider comes from Green Bay, where the Packers' 53-man roster and IR list averages 26.48 years old based on exactly how old each player was Wednesday (as opposed to rounded down ages listed at the beginning of the season). The Seahawks have the third-oldest team by this criteria. The Cardinals have the oldest. The Rams are third-youngest. The 49ers are 23rd-youngest.
Arizona could stand to get younger at outside linebacker. Seattle is quite a bit older on offense than on defense. The Rams, young as they are, could stand to get younger at defensive end, where James Hall and Leonard Little were key players last season. The 49ers have some age in isolated spots on defense, including at linebacker (Takeo Spikes) and in the secondary (Dre Bly, the injured Walt Harris).
