Walter Football ran through it's list of the Green Bay Packers 2013 team needs and I pretty much agree with it, though it's somewhat of a surprise to see wide receiver listed ahead of outside linebacker. However, GM Ted Thompson has been known to draft wide receivers early, even when it didn't seem like an obvious need, which is important because QB Aaron Rodgers isn't nearly as good if he can't trust his receivers. While the Packers need to replace LB Erik Walden, the return of 1st round LB Nick Perry should be the answer to that problem. Adding depth might be important but that can be addressed later in the draft, and I'll be interested to see if LB Dezman Moses can improve next season because he has potential.
The one position not mentioned by Walter Football was the defensive line, which should not be overlooked. Their only current lineman with any star potential is B.J. Raji and he hasn't been his best over the past two seasons. Also, the other linemen (Ryan Pickett, C.J. Wilson, Mike Neal, Mike Daniels) are a collection of role players. There isn't an every down lineman on the roster except Raji. The possible loss of Jerel Worthy for the entire 2013 season isn't going to help either.
Another reason to target the defensive line is that it's the deepest group in the 2013 draft. There should be a lot of defensive lineman taken early. At the end of the 1st round, the Packers might still be able to find a great defensive lineman available, similar to their 2010 selection of Bryan Bulaga (he was the sixth offensive lineman taken in the top 23 picks).
This is also a good draft for offensive lineman and the Packers have a glaring need at center. However, GM Ted Thompson hasn't used a 2nd or 3rd round pick on an interior lineman since 2006 (Daryn Colledge, Jason Spitz), so it's a position I expect he'll fill later in the draft.
As Todd McShay wrote about 2013, "It's not a good TV draft" so it's not a year to draft a quarterback or running back early. Which is perfect for the Packers because they need help and depth at the two positions that are loaded in the draft; offensive and defensive line. The addition of a top tier running back would be a big help too, but it doesn't look like that caliber of player is available in the 2013 draft. However, the players they likely target next April on either the offensive or defensive line will probably provide an immediate boost and will probably represent a great value relative to the Packers' position near the end of each round.
