Is there a reason for the restructures or just getting extra cap flexibility?

Is this extra cap space from the Boom and AD restructure for particular players or just cap flexibility? Secretly I am hoping they need the space for either an already behind the scenes for an edge to be acquired in trade or for Clowney/Chase. They also can now go get Spoon or Gilmore if they consider him an upgrade over the next 3 years at the opposite CB position and maybe JJIII as well. We will see.
