Aaron Curry, I think by far. Just because of what the Browns did in this draft. Trading down 3 times from #5 to #21 picking up 2nd Rounder and 2 6th rounders.
Seahawks could have got:
#21 C, Alex Mack
Still trade original 2nd to Denver
#52 OT, Sebastian Vollmer
Trade 3rd Rounder for 2010 2nd Rounder
#105 OT, TJ Lang
Don't trade for Keary Colbert, but package the 5th and 2 6ths for 2010 4th Rounder.
End the draft with Jason McCourty, Julian Edleman, and Michael 'freakin' Bennett over Nick Reed, who we develop.
Trade the 2010 #6 plus the extra 2nd and 4th we acquired to the Redskins for OT, Trent Williams.
Don't trade for Charlie Whitehurst instead take TE, Ron Gronkowski at #40.
Trade up 2 spaces in 3rd to select OT Jared Veldheer using that 6th rounder we used trading for Lendale White.
Trade back up into the 3rd Round using the pair of 4th rounders to select LB Navarro Bowman.
Trade 2011 1st and 3rd Rounder , 2013 1st, 3rd Rounder, and 7th rounder + 2015 1st Rounder to the Browns for #5th pick. Select Julio Jones. See what I did there.
Make same trade with Detroit with our 2nd but end up with
DT Jarell Casey
LB KJ Wright
TE Julian Thomas
CB Richard Sherman
CB Byron Maxwell
Let's say Seahawks win 10 games instead of 7 in 2010 but still end up with #25 losing to Chicago. 2011 is still an injury riddled let down with no QB, still nets us #12 in 2012.
2012... exact same draft.
We don't over spend in 2011 bringing in Rice, Miller, and Gallery instead saving cap for upcoming big time free agents.
Offensive Line would look like:
OT Trent Williams
LG Jared Veldheer
OC Alex Mack
RG TJ Lang
RT Sebastion Vollmer
Skill position players that include Lynch, Jones, Baldwin, Edleman, Gronk, and Julian Thomas.
2012 DL that is more of a 3-4 base, 4-2 Nickel... Clemons, Wright at OLB, Bowman, Wagner at ILB. Starting Branch, Mebane, Bryant at DT. With Casey, Bennett, and Irvin coming in as reserve/specialists.
Win 5 straight Superbowls from 2012-2016, because of not drafting Aaron Curry.
