I think the Packers could use another OT worth but teams probably can't get fair market value right now for them because they're such an important position and some other teams are in even more need for them.
Packers do need someone to step up as the starter with Williams at CB, but i think the Packers have good enough options there to stay put. With Shields, House, Bush, Hayward and maybe Ross.
Also think the DB depth is good enough with McMillian, Jennings, Levine and Richardson, only questions there is who do they cut? Because they also have Burnett and Woodson at DB... Richardson looks like he's last of the group but he's a rookie almost competing with them and showing more in his rookie year than Jennings or Levine did as rookies, so might keep him based on potential and not risk losing him.
Where I'm more worried is RB. An article said Starks isn't getting better, Saines disappeared and other RB look pretty average...
Also I wouldn't mind trading Jones, I like him as the safety net, but there are only so many passes to go around, he's in his prime, he wants more chances, it'd be nice to get a draft pick and keep the younger guys who'll also be cheaper and coach them up. It's a win-win as long as the draft pick is high enough.
