Emmons aches

Did the Eagles' medical staff see something in their treatment/recuperation of Carlos Emmons' broken leg that led them to believe it would be a chronic or nagging injury well past the normal recovery time? Did it have any bearing on the personnell side's decision to let him depart via free agency? Those questions have been raised in my mind after seeing reports that Emmons missed three straight practices with the Giants last week because of pain in the leg he broke in the Niners game late last year.
