The Cardinals have signed 32-year old OLB Joey Porter to a 3-year, $17.5 million with an additional $7 million bucks in possible incentives.  Porter played in 14 games for the Dolphins last season in which he made 41 tackles, defensed 1 pass, had 9 sacks and he forced 1 fumble.  He has now played in 168 games in his NFL career in which he has made 601 tackles, defensed 50 passes, has 92 sacks, forced 24 fumbles and he intercepted 12 passes (one returned for a TD).  I like this signing for the Cardinals if Porter has a lot left in the gas tank, but, only time will tell if he does or not.
