I don't disagree outright. Yes, Bob and the other 31 have the vast, lion's share of the blame. Further, he and some of the other owners, IMHO, probably thought 'I don't necessarily like how it is going BUT this is how it is. The business/revenue is growing, that is what matters, don't rock the boat'.
However, isn't there room for nuance beyond that? Goodell is in fact untouchable even to powerful Bob, to a powerful group of 4 or 5 owners, by the media, or by fans. Short of committing theft, rape or murder I don't think Goodell can get fired. He has solified power to a degree that is pretty astonishing when you consider he reports to 32 billionaires. So if there isn't room for nuance, aren't loyal NFL watchers/users -- Us -- also to blame on a small level? We keep Goodell's numbers high enough to make him untouchable. Consider this, if just 3% of us turned off the TV, the networks would wail and Goodell would probably be replaced by end of season.
Someone here smartly said a liberal is a conservative who has been arrested, and a conservative is a liberal who got mugged. This cluster F with Goodell at the head, this thing is much bigger than Bob and what Bob can do about him. Other sport's leagues have powerful commissioners yet this guy, Goodell, IMHO only, is a snake in the grass who snuck up on even the powerful like Bob.
With that said, I do not absolve Bob of blame but I semi disagree if we can't also look at circumstance.
