The Dolphins have signed 33-year old DE Marques Douglas to a 2-year, $2.5 million dollar contract.  Douglas played in 16 games (12 starts) for the Jets last season and he had 64 tackles, 1.5 sacks and he forced 1 fumble.  He has now played in 120 games (91 starts) in his NFL career and he has 435 tackles, 20.5 sacks, he defensed 10 passes and he forced 7 fumbles.  This was a much needed addition for the Dolphins after the recent loss of Phillip Merling.
