Demoff didn't create these technique or loopholes as he simply was able to apply them for the Bucs situation. The Vikings were the first to heavy employ such an approach with regards to the cap.
That's not true. Demoff did create many techniques and loopholes that a lot of NFL teams use now like I said in my previous post about him. He didn't invent the techniques talked about in the article, and that's not what I was referring to about him.
