Just from memory, Daniels is the most bang for your buck ($8M+), meaning cutting him gives the Packers the most money. A few of us have been debating cutting Crosby in other threads and while some think cutting him wouldn't be painful, I'm not so sure about that, as well as the amount of cap savings you get back after replacing him, doesn't buy you a whole lot.
Tramon Williams has been mentioned, but now that I look up his salary details, he has already earned $1M of his roster bonus by being on the team as of 3/15, so he might not be on the cut radar either, since doing so appears to only net the Packers $2.625M.
Bottom line for me, I wouldn't cut Daniels, Bulaga, Williams, Crosby, etc. unless 2 things happen. First, the Packers are pretty certain they have an equal replacement on the team. Second, the player they use that money on improves the team more than losing said player. Baldwin or Chancellor IMO wouldn't be worth parting ways with any of those guys.
All that said, if I had to lay money on a cut, I would say it would be Daniels. Mainly because of how much money that frees up and I think the DL could absorb the loss better than the other positions.
