If Rodgers is gone it means a complete rebuild. The dead cap is about 2x his salary. Basically we would have to start cutting everyone not on their first contract and just throw in the towel for a year to get out from under the mess.
I have no idea how the dollars work, but I've seen plenty of sites on the internet that indicate it would be smart for the Packers to trade Rodgers now. Actually it sounds like it would have been smarter last year, but this year would be better than next year.
But as I said, I have no idea how the dollars all work.
