The Cowboys will be without starting LG Kyle Kosier for the next 4-6 weeks due to a sprained MCL.  This is a pretty big blow for the Cowboys who are already without RT Mark Columbo.  Kosier has started 51 games in 4 years with the Cowboys including all 16 in 2009.  30-year old Montrae Holland will likely replace Kosier until he’s ready to return to action.  Holland did not get into any games last season for the Cowboys.  He has played in 7 games (2 starts) in his two years in Dallas.  Holland has played in 75 games (48 starts) in his 7 years in the NFL.  I have a feeling that Holland will do a decent job while Kosier is out of action but it will still be a dropoff for the Cowboys’ O-Line.
