The below is my ideal Redskins starting offense for 2012 which includes the draft and free agency. I believe Shanahan will take his QB in the first round in Barkley (assuming he enters). Any other starters will most likely have to be added in free agency.
WR1 - D.Bowe (FA-KC. Shanahan must give Barkley a No.1)
WR2 - Hankerson (could be in for a breakout season if Bowe is added)
Slot - Moss (still has gas left and could be deadly in the slot)
TE - Davis (re-signed - $ reduced a bit and with an opt-out clause due to the suspension. Still a top tier TE)
RB1 - Helu (the future)
RB2 - Hightower (the future's backup)
FB - Young (has done well this year. overtaking Sellers in the off-season is saying something)
QB - M.Barkley (draft-USC. Debatable if he's the No. 2 or 3 QB in the draft, but still light years ahead of Rex)
LT - Williams (good, not great, but hoping he improves in yr 3 and stays out of trouble)
LG - Lich (re-signed. OL wasn't the same when he went down)
C - Montgomery (re-signed. Knows the system)
RG - B.Grubbs (FA-BAL. Need help on the interior. Who better than one of the top OG)
RT - Brown**
**Brown needs to be replaced, but there isn't a lot talent at OT in FA. Plus, Shanahan will still need to address other positions in FA in the secondary. He could address the OT position in the 2nd round, but most likely anyone taken there won't be able to start right away. Hopefully someone on the bench steps up instead.
