The Cardinals have signed 30-year old center Melvin Fowler to a 1-year deal.  The 6’3″, 310 pound Fowler played in 15 games (5 starts) for the Bills last season.  In his seven year NFL career, Fowler has played in 87 games (60 starts).  This was a good signing for the Cardinals as Fowler will provide quality depth at both center and guard.
