Free-Agent Setup: Seattle Seahawks seek to keep DT Sheldon Richardson

The Seattle Seahawks' only logical candidate for a franchise or transition tag is defensive tackle Sheldon Richardson.

Richardson was acquired from the New York Jets last September prior to the start of the regular season and cost Seattle a second-round pick and wide receiver Jermaine Kearse in return. The Seahawks and Richardson expressed mutual interest in keeping the relationship going into the future.

However, a franchise tag amount of approximately $14 million could prove prohibitive. Tight end Jimmy Graham is coming off a 10-touchdown season, but the general sentiment is both sides are ready for a change.
