He is not actually a Saints castoff so much as a Falcons castoff as he never actually played for the Saints.  He is more of a pass rushing DT but he had great technique and was still solid against the run.  He is just not a two gap type guy but he didn;'t have to be bc he played beside Grady Jackson for all of 2006 and half of 2007 (before Grady got traded to the Jaguars midseason).  But to be honest Grady's technique was not that great he was just HUGE, so if he succeed next to him he may have something left.  He is coming off of an injury though so....... Also he is only like 290 or something and 6'2".
