I believe this is how the Packers look at needs, as they so often draft a position where an important player is in a contract year.
So where as fans would say we have no need at Safety as we have Amos and Savage. Packers would say we do have a need at Safety because Amos is in a contract year and potential might not be back, we need to develop a guy now. Also if they don't pick up Savages option then he's also in a contract year. Plus the 3rd Safety can be asked to play more than 25% of snaps and the Packers seriously need a 3rd Safety either way.
Though I might add the players that will be RFA and ERFAs too (assuming they're talented enough to help and stick around), as if the Packers want them back, they can keep them for reasonable contracts.
I believe the RFAs will be
WR Malik Taylor
TE Dominique Dafney
TE Tyler Davis
OT Yosh Nijman
ILB Krys Barnes
OLB Randy Ramsey
I believe the ERFAs will be
RB Patrick Taylor
WR Juwann Winfree
C Jake Hanson
OLB Tips Galeai
S Sean Davis
LS Steven Wirtel
Based on all these roster, I say Packers needs appear to be (to me)
1) WRs (need muliple with Cobb, Lazard and Watkins all in contract years)
2a) OT (need a 3rd OT in case of injury and to compete with Nijman and Newman for starting jobs)
2b) S (3rd Safety plays 25% of the time and potential future starter with Amos in contact year)
4) DT (Lowry and Reed are in contract years and we need better depth anyways, especially with our defensive play caller liking to often go with light 6 man boxes).
5) OLB (Gute values position value, and OLB has a ton of position value, so it wouldn't surprise me to see this go higher especially since this year has a lot of good edge rushers, but the OLB coach has said he wants a 4 man rotation at OLB, I think getting a healthy Ramsey back will be huge, as he was behind Gary before his injury)
6) LS (I don't trust our LSers, though position value will have this a lot lower)
7) IOL (depends on how comfortable one is with Hanson as backup and Jenkins coming back later in the season, also ideally we'd get an OT that could also play OG if he doesn't win a starting OT spot and ideally Runyan, Myers and Newman all improve as they're young and got to play a lot last year)
8) CBs (Alexander is in a contract year and didn't stay healthy last year, but we clearly need more depth.
9) TE (TE, I truely want to put TE higher with Tonyan and Lewis going into contract years, but we have Dugara, Dafney and Davis all returning which gives us solid depth and not really a clear extra spot, unless someone (Tonyan) is expected to start the year on the PUP list). Also Packers seem to grab large WRs which some can be used a receiving TEs and they seem to be working in WR Rodgers as a versatile WR/RB/FB which is basically an H-back (which is a type of shorter TE).
10) RBs (Packers are good at RB, but could always upgrade the #3 RB spot when a RB falls further than expected, as RBs often get injured)
11) Kicker and Punter (no need unless there is a clear upgrade to be had and to save cap money)
12) QB (no need at this point)
