Redding provides some much needed experience in this defense, but isn't exactly entering his prime, the rest are all DT's playing DE, Nevis looked good last year, when healthy. Not much depth here, don't think Ogbu is a good fit for DE
Johnson will probably start out the year and eventually backup Chapman, McKinney is a huge body with experience in this defense. Johnson might be a better fit at at DE, not alot of depth here either.
Should be a very interesting position, I think its a great fit for Mathis, not sure about Freeney. Could be a savior for the yet-to-produce Hughes, (repeat) not alot of proven depth here
Angerer and Conner will be tackling machines in the middle. No depth here at all, I like Galippo over Harvey
