It makes perfect sense, and you can't do it.
2K has set up the file control so that you can't save or snapshot a game file, on your own console (locally) or in some cloud service in their server system (or with Sony or Microsoft, for that matter).
I have lost two long term MyLeague files to corruption this way. There's no backup anywhere to restore from, and the only file save mechanism is the autosave. If your file is corrupted in the one file save 2k service, it's gone for good.
So if you want to progress your game file, you have to go with whatever scenarios play out, unfortunately.
A lot of people have brought this up as a sore point with 2k, so we'll see if they make an accommodations with 2k16.
