Chickillo already went through waivers once and no one wanted him last year.
I'm pretty sure Feeney and Matakevich will make it through waivers as well. Feeney is WAY too undersized to make an active roster right now. And players like Matakevich is pretty much grow on trees. He might fill up a college stat sheet, but that doesn't mean much in the pros if those tackles are after successful offensive plays.
Just is what it is.
I'm not sure Freeney fits here right now. Still have Moats and Harrison as our veterans. I would think Freeney would be better off in someplace like Atlanta or New York Giants that like to rotate defensive lineman A LOT. Use him as a pass rush specialist on turf with his hand on the ground. Maybe New Orleans too. Even New England might be able to find a spot for him since they got rid of Chandler Jones. Can use him the same way.
