The difference is that the Bucs are bringing back a team that won the Super Bowl, and the Packers are bringing back a team that has had its flaws exposed in the NFC title game two years in a row, at the expense of actually addressing those flaws.
None of these moves in and of themselves are bad. It's good to have Aaron Jones on your team. There is a role for Mercedes Lewis on the team. Kevin King can play a role in the secondary. What's so disheartening is the overall attitude of "good enough" from the FO, and the seeming blindness to real roster holes that exist which can't now be addressed because they brought back everyone that was just good enough.
