The Facts: Seattle signed Griffith, a free-agent fullback, to a one-year contract Monday.

Diehards Line:Griffith was a fourth-round pick by Atlanta in 2003. He spent the first four years of his career with the Falcons, the final three for current Seahawks HC Jim Mora and OC Greg Knapp, then signed with Oakland in 2007.
