Copied and pasted from espn insider. I will give it two minutes before the first Steeler fan will post a complaint about not being considered "the best"
Best value pick: CB Lardarius Webb (2009: Round 3, Pick 88)
Cornerstone picks: CB Jimmy Smith (2011: Rd. 1, 27); OT Michael Oher (2009: Rd. 1, 23)
The Ravens' draft success certainly predates 2009. Both QB Joe Flacco and RB Ray Rice are blues from previous classes, but they've also added two more in Webb and Smith, two corners that Baltimore badly needed. Both CBs are solid in man-to-man coverage, as you have to be in the Ravens' system.
If they had a blue WR they likely would have been in the Super Bowl. Torrey Smith may be it.
The big question mark is Sergio Kindle (2010: Rd. 2, 43) who has missed time due to an off-field injury. If he can come back and produce as some believe he can, he could be another blue.
Best value pick: DB Louis Delmas (2009: Rd. 2, 33)
Cornerstone picks: QB Matthew Stafford (2009: Rd. 1, 1), DT Ndamukong Suh (2010: Rd. 1, 2)
The Lions have blues all over the place, which they should, having drafted as high as they did for several years straight. Still, you can miss high, and we've seen a great job by GM Martin Mayhew and coaches Jim Schwartz and Rod Marinelli to make picks that fit into their system.
If RB Mikel Leshoure is the real deal coming back from injury, they are ready to contend at a higher level. I'd look for another solid RB and O-line help in the 2012 draft just to be sure they have what they need.
Green Bay Packers
Best value pick: WR Randall Cobb (2011: Rd. 2, 64)
Cornerstone picks: DT B.J. Raji (2009: Rd. 1, 9), LB Clay Matthews (2009: Rd. 1, 26)
A big blue pass-rusher, plus a speedy pass-rusher, coupled with a blue QB and the two blue WRs equals a Super Bowl. It's simple math! The secondary could use an infusion of top young talent. GM Ted Thompson, head coach Mike McCarthy and defensive coordinator Dom Capers work together as well as any group in the league to draft and deploy talent.
New York Giants
Best value pick: WR Hakeem Nicks (2009: Rd. 1, 29)
Cornerstone pick: DE Jason Pierre-Paul (2010: Rd. 1, 15)
Eli Manning and a revamped receiving corps coupled with a great pass-rushing defense featuring blue-chippers up front and in the secondary garnered the Lombardi trophy. Terrific job by Jerry Reese and company to build a second Super Bowl team in four years.
Keep an eye on 2011 first-round CB Prince Amukamara. He's unproven after missing most of his rookie year to injury, but he has upside and could enter blue territory.
San Francisco 49ers
Best value pick: LB NaVorro Bowman (2010: Rd. 3, 91)
Cornerstone pick: DE Aldon Smith (2011: Rd. 1, 7)
This team is driven by its defense, which features multiple blue-chip playmakers. You can't play this defensive system without a dynamic outside linebacker who can rush the passer. Smith was the finishing touch to their defense last season.
Offensively the 49ers are propelled by the running game. A step up by WR Michael Crabtree and the addition of another playmaker at WR would help greatly.
