The Jets have signed 31-year old DE Marques Douglas.  Douglas played in all 16 games for the Ravens last season and he made 36 tackles.  Douglas has now played in 104 games in his NFL career and he has made 372 tackles, defensed 10 passes, has 19 sacks and he has forced 6 fumbles.  He should provide good depth on defense for the Jets in 2009.
