LG: for sure...among Thomas, M Martin, Looney and a rookie.
WR: T Smith replaces Crabtree and/or Johnson with Ellington, Patton and a rookie pushing.
RB: Hyde, Bush, rookie (Hunter may compete but he isn't likely our new bell cow).
TE: VD needs to reprove himself and stay healthy but a TE with a bad back is a problem. McDonald competes? Or a rookie? Celek and Carrier are good backups.
These are major changes and could be really exciting or perhaps take while to develop. Of course I'd prefer the former!
Just to throw it in, why not just say you believe the NFLN poll sating the Raiders will have a better record than the Niners this season.
