Tobias, I think you're confusing anger with the league with the actual decisions and results from Bruce Allen and Mike Shanahan.
It doesn't matter what the league said, or did, prior to the Redskins moving all the cap money to the uncapped year. The front office was well aware that very few other teams were doing this, and that the ones doing it were doing so on a much more limited basis than the Redskins. They do not work in a vacuum; they keep an eye on what their competition does; they attempt to gain competitive advantage when they can. They knew they were outliers, by a mile. And they knew the reason --- fear of league repercussion.
Dan Snyder also knew he would never take the NFL to court over the issue. You can be sure that the legalities of using the uncapped year as a salary dump were checked out and discussed in advance by the front office, unless the defense of them is that they were inoocent dummies. When the time came to challenge the NFL after the cap hit was applied, they hemmed and hawed and folded. Snyder was never going to challenge the league legally. That's on him.
The salary-dump-in-uncapped-year idea, however, is directly on Allen who came up with it and Shanahan who signed off on it. It failed. They're responsible. They sold and signed off on the idea, respectively.
Now, back to the real question. We talk about a $36 million cap hit over 2 years. What was the cap hit without all the salary cap maneuvering, and without the resulting league penalty? What years were they previously obligated to pay that $36 million in salary, and how much each year? Some of it would have been in 2012, some in 2013, and probably some in future years. Anyone know?
