Who takes over? What does that solve? Roger is nothing more than a figurehead of what the owners want. You can put whatever suit you want up there, but you're going to get the same thing.
I disagree with this presumption. That presumes that there is only one way to be a corporate suit.
I could use the Costco v. Sams Club comparison. Walmart corporate suits are VERY different than the Costco corporate suits in some ways, but behave very similarly in others.
I could see a Commish that focused on actual player safety, stability with the relationship with the NFLPA, building non-traditional commercial relationships, building a female fanbase (which has the added side effect of ensuring that kids still play football), growing traditional corporate partnerships, growing the NFL's media footprint via traditional and new media opportunities... all while having integrity.
There are billion dollar businesses that operate with a reasonable amount of transparency and do function with integrity. The NFL doesn't have to settle for Roger Goodell as if his incompetence and lies are the pinnacle of corporate governance.
