The Patriots have signed 28-year old linebacker Tully Banta-Cain.  Banta-Cain played the last two seasons with the 49ers after leaving the Patriots as a free agent.  He played in 12 games for the 49ers last season and he made 18 tackles and had 1/2 a sack.  Banta-Cain has now played in 82 games over his NFL career and he has made 150 tackles, defensed 3 passes, has 12.5 sacks, 1 forced fumble and he has 1 interception.  This was a good move for the Patriots as Banta-Cain will give them depth on defense and he will help out on special teams.
