The Broncos have released 36-year old center Casey Wiegmann.  Wiegmann started all 16 games for the Broncos last season.  He started all 32 games in his two years with the Broncos.  The Broncos are not a zone blocking team anymore as they want to go with more of a power blocking style.  With that in mind look for Wiegmann to possibly surface with a team like the Texans or Redskins in 2010.
