(Renton, WA)  --  Seahawks head coach Pete Carroll says Marshawn Lynch appears geared for a big second half of the season.  Carroll says the star running back is in "very good shape" for mid-year and is excited about playing.  Lynch, who missed two games and most of a third with injuries earlier in the season, was held out of practice yesterday for non-injury-related issues.  The Seahawks are getting ready for Sunday's prime-time game with the Arizona Cardinals at CenturyLink Field.
