Seahawks experience most roster turnover in the league

Bad teams tend to change coaches and overhaul their rosters.

It should come as little surprise, then, to see the Seattle Seahawks retain a league-low 66.1 percent of their players from last season. It should likewise make sense to see the NFC North champion Minnesota retain a league-high 94.4 percent over the same period.

But when the two-time defending NFC West champion Arizona rank right behind Seattle and the Detroit with a 70.2 percent retention rate, third-lowest in the league, we gain context for the magnitude of change in the desert. Anquan Boldin, Kurt Warner, Antrel Rolle, Karlos Dansby, Bryant McFadden, Mike Gandy, Chike Okeafor and Bertrand Berry combined to start 107 games for the Cardinals last season. All are gone.

Not that change is always bad, even for good teams.

Seattle (.661): New coach plus new general manager plus a mandate for change leaves the Seahawks with only 39 players on their roster from Week 17 (counting those listed on IR). Every other team in the league has more. The league average is 49.4 players back.
