To the JJ apologists: Are you happy with him? We still should blindly support him?
To the Cowboys fans: Take a break - don't come to the games. Take your frustration to social media. Let the sports media finally report a loss of fan support for the Cowboys. This is not necessarily to walk away forever...sometimes you have to get tough with the things you love. Over a decade ago, when JJ was concerned no town would help him build his billion-dollar stadium, he mostly (but not completely) left things alone by hiring Bill Parcells and bringing a few winning seasons. That indicates JJ does respond to fan pressure and loss of revenue.
So stop enabling JJ - as long as you come to games after they choke time and again, you support mediocrity - the antithesis of what was America's Team. Paying JJ is endorsing performance like yesterday's game - period. This is the only thing that has not been tried. Isn't he committed contractually to play at Cowboys Stadium for the next 30 years? i.e. he can't move.
While historically a chance JJ will respond to fan pressure, it's also possible he could dig his heals and end his days like the late Al Davis did...if he insists on punishing himself, so be it. If he chooses to do it "My Way" in the face of fierce fan pressure, his son will take note.
It should already be obvious - the only way JJ has ruined this team is fans come to see the games regardless. Stop going, and at some point - may be a long time, this will stop.
