I wouldn't be completely surprised if we traded/released Shields. TT doesn't seem to have a problem moving on from DBs when he feels like he won't get particularly good value for them (Davon House, Casey Heyward, Tramon Williams, etc). That being said, he did resign Shields to a 4 year $39 million contract so perhaps he's more the exception here.
I will say Burnett might also be a guy who we considering moving/releasing though. We are paying him $7 million next year, and while I don't dislike him I'm not convinced he's worth that price. Freeing up $5-$6 million would give us about $30 million or so of free cap space overall to work with (according to "
http://overthecap.com/salary-cap/green-bay-packers"...may not be entirely accurate though).
