The Rams have acquired 26-year old OLB Bobby Carpenter from the Cowboys for 27-year old OT Earl Barron.  Carpenter played in 16 games for the Cowboys last season and he had 46 tackles, 1 tackle for a loss, he had 2 sacks and he defensed 1 pass.  He played 4 years with the Cowboys in which he played in 58 games finishing up with 96 tackles, 2 passes defensed and 3.5 sacks.  Carpenter will likely start at one of the OLB spots for the Rams in 2010.  Alex Barron started all 16 games for the Rams last season and he has played in 76 games (74 starts) in his five years with the team.  Carpenter will probably be a pretty good upgrade at OLB for the Rams and for that reason I like this trade for them.
