(Renton, WA)  --  A picture of a pair of lime-green football shoes hanging over a wire appears to indicate that Seahawks running back Marshawn Lynch is calling it a career.  The photo appeared yesterday on Lynch's Twitter account during the Super Bowl, and followed reports that he told people close to him he's retiring.  Lynch has played nine seasons in the NFL and was selected five times to play in the Pro Bowl.  His contract with Seattle runs through 2017.
