The Cowboys have signed 33-year old linebacker Keith Brooking to a 3-year contract.  Brooking played in all 16 games for the Falcons last season and he made 102 tackles and defensed 3 passes.  8 times in his 11 year NFL career Brooking has made more than 100 tackles in a season.  Brooking has now played in 161 games in his NFL career and he has made 1,127 tackles, has defensed 46 passes, has 17 sacks, forced 8 fumbles and he has 12 interceptions.  Brooking’s signing will probably end Zach Thomas’ time in Dallas.
