Many of the prospects you've listed aren't draft eligible in 2011, and you've left out some. My list (juniors with an *):
QB Jake Locker, Washington
QB Ryan Mallet, Arkansas (still could declare for 2010)
RB Mark Ingram*, Alabama
WR Julio Jones*, Alabama
WR AJ Green*, Georgia
WR Jonathan Baldwin*, Pitt
WR Michael Floyd*, Notre Dame
OT Matt Reynolds*, BYU
OT Clint Boling*, Georgia
DE/DT Cameron Heyward, Ohio State (still could declare for 2010)
DE/DT Allen Bailey, Miami
DT Brian Price, UCLA (still could declare for 2010)
DE DaQuan Bowers*, Clemson
DE Robert Quinn*, North Carolina
DE Aldon Smith**, Missouri (red shirt sophomore)
LB Travis Lewis, Oklahoma (could still declare for 2010)
LB Bruce Carter, North Carolina
ILB Rolando McClain, Alabama (still could declare for 2010)
S Eric Berry, Tennessee (still could declare for 2010)
S Earl Thomas, Texas (still could declare for 2010)
CB Patrick Peterson*, LSU
CB Joe Haden, Florida (still could declare for 2010)
That's 22 prospects, of whom 8 could still declare for 2010. Most of those are likely to come out this year, but it's not a sure thing. Even so, that leaves 15 or so players. Disregarding the guys who are likely to come out in 2010 (such as Eric Berry, Joe Haden and Rolando McClain), that leaves 5 major options that I see:
1. CB Patrick Peterson from LSU. Possibly the best CB prospect since Champ Bailey, almost certain top 10 pick.
2. A pass rushing DE/OLB like Robert Quinn from North Carolina or Aldon Smith from Missouri.
3. A 3-4 DE prospect like Cameron Heyward of Ohio St., who is eligible in 2010 but seems to be leaning towards returning right now, or Allen Bailey.
4. One of the "big 4" WRs: Jones, Green, Baldwin and Floyd.
5. An OT like Reynolds or Boling. I think this is the least likely.
Ideally, I'd like to see us pick one of CB Patrick Peterson, DE/OLB Robert Quinn, or DE Cameron Heyward with the Raiders pick, and then trade up from our own pick to get one of the top 4 WRs. Baldwin is my personal favorite. But with 4 of them, one is likely to slip out of the top 15-20. There are also other very talented WR prospects like DeAndre Brown who may be available towards the end of the 1st round because of all the WR talent.
