The game itself is about strength. These are athletes capable of doing things no previous athlete who has ever played football has been able to do. But the NFL's understanding of itself, and to a great degree what they've been selling - is not about strength, it's about power. You don't need to be physically strong, you don't need to be Cam Newton, to be powerful. You can be a soft, pink man in an owner's box, and you can fire Cam Newton. And he can't say no to you.
