I haven't seen anything definitive, but seems to be talk that the Raiders signed Kalimba Edwards

PT (Franklin, NC): With the signing of Kalimba Edwards, should the Raiders consider moving to a 3-4 D and using him as an OLB?

 Jeremy Green: (12:06 PM ET ) The Raiders have become like a lot of teams such as Baltimore, New England, Arizona what I would define as a Hybrid type defense. Rob Ryan came from New England. The Pats use more 3-4 then 4-3 where as the Raiders are more 4-3 then 3- but will use both. So Edwards will play some DE and OLB in Ryan's system.

Has anyone else heard this. There is also a rumor of CJ to Oakland for next years 2nd and 3rd and Fabian
