Restructures mean nothing in terms of something being on the brink of happening.
Look at it this way.
A player has 4 years left on deal. Ten million dollars is converted to bonus so now its spread amongst this year, and the remaining three years. Cap savings of current year would be 7.5 million.
Guy is cut after year 2 of restructure. That means the dead money increased 5 million dollars when you go to cut him, because you already accounted for the 2.5 million in each of the prior 2 years.
The Bills rolled over the cap savings from the restructure so now have an additional 5 million when you go to cut him.
End of the day, it costs you nothing more against the cap than it would have been since it is a higher dead cap, but you have more roll over. However, in the current year of the restructure, you have a cushion just incase you need it.
