The only guys entering free agency in 2015 that, as of right now, I would think the Packers would be interested in keeping at other than minimum deals, would be Nelson, Cobb, Raji, Williams, Bulaga, Sherrod and maybe Tolzein. Of those, I could only see Nelson and Cobb really getting large deals. You could just as easily model Nelson's deal after Mike Wallace if you needed to. Wallace is paid most of his guaranteed money in the first few years and, while Wallace's cap numbers in the final two years are $13.7m each year, the dead money is only $4.4m in 2016 and $2.2m in 2017.
If you actually look at the potential free agents coming up over the next couple years with some honesty, there aren't really a TON of guys that we have to re-sign. In 2015 you have Nelson, Bulaga (hopefully he plays like he did two years ago), maybe Williams (but cheap), Sherrod (hopefully also cheap and if he shows himself recovered) and then in 2015 you have Daniels, Perry, Worthy (maybe) and Hayward. Right now the team only has $87m spent on the 2016 cap, well below the projected $150m cap for that season. No reason that nelson can't get a substantial amount of his guaranteed money early and alleviate fears of dead money later in his contract.
