QB: Brady Quinn- (if he's cheap) I feel he can be a capable backup behind Rivers for years to come. He could benefit from watching an elite QB day in and day out.
RB: Ronnie Brown- I think he would be an upgrade over Tolbert if we let him walk. He's versatile and can teach Matthews a few things, since Matthews never had a veteran RB to learn from coming in to the NFL.
WR: Reggie Wayne- He is a good route runner and wasn't as productive this year without Manning. He would be a good slot WR and would be able to mentor Vincent Brown (since they are around the same size and have the same skill set)
TE: Kellen Davis- Was used more as a blocker with Mike Martz offense, but I believe he can be a good receiving threat. He is an upgrade over McMichael IMO. Can learn a lot from Gates.
