The Cardinals' roster became a little more whole when Kurt Warner agreed to terms on a new contract. I've updated each NFC West team's 26-column roster to include that move and every other move in the division to this point.
The Seahawks' and Rams' rosters have the most potential for turnover through unrestricted free agency in the division. I calculate turnover potential by adding the following totals for each team:
Unrestricted free agents signed from other teams
Unrestricted free agents leaving for other teams
Players acquired by trade
Players lost by trade
Unsigned unrestricted free agents
I then subtract the number of UFAs who have re-signed with each team. The higher the remaining number, the higher potential for change through free agency. This is an imprecise method of measurement but it does give me a feel for which teams are experiencing significant turnover. The teams with the four highest numbers all have new head coaches.
The league average was 9.9 through the Warner signing. Denver (22) and Detroit (21) had the highest numbers, followed by the Seahawks (17), Rams (16), Patriots (15) and Jets (14). The 49ers (10) and Cardinals (8) are right around the league average.
The Broncos are in high gear. By my count, they have signed 10 of the first 39 unrestricted free agents who have changed teams this offseason. Seven of the 10 are in their 30s. The rest of the league has signed a combined three UFAs in their 30s from other teams: T.J. Houshmandzadeh (Seahawks), Moran Norris (49ers) and Keith Brooking (Cowboys).
Note: I have not updated starting lineups recently. That information is incomplete.
