It's bad enough that you act like you can speak for the owners but it's that much worse that you act like they all think with the same brain. I'm sure that some like Richardson may take that tactic but that is not certain nor is it a universal sentiment.
There is still a strong enough old guard that could block something like this.
Old money owners are not equipped or inclined to deal with something like this. In addition to Richardson, the Rooneys, Hunt, McCaskey, Mara/Tisch, Bidwell, Brown, Benson and Martha Ford fall in that group.
I know it is nice to pretend that Jerry Jones really controls the rest of the owners like puppets, but this is a substantial policy change with significant PR impact to your average owner to take on. Until it becomes even more mainstream than it is now, like another collection of states passing relaxed laws, it is highly unlikely for the NFL to get comfortable with it. Things move slowly in the NFL and something this socially significant is not something that Jones can negotiate all by himself.
If you doubt that, all you have to see how players like Eugene Monroe were effectively blackballed once they started speaking out about it. The vast majority of people still subscribe to the idea that it is dangerous, despite your impression that it is sweeping the nation.
