Are you gonna let the owner Patrick Dumc**t and Nico Harrisonuvab***h hijack and run your franchise into the ground?

I'm loving the "Fire Nico" chants but I think you also should include owner. It starts at the top and this buffoon was the one to approve the trade.
If you fire Nico, the owner will just hire another idiot. And I doubt he'll fire him since he's Patrick's useful idiot. This guy does not want to win, does not want to build something, it's a pure money-making business play and nothing else to him. That's obvious af.
Instead of fans leaving the team, run Dumont out of town and never let up until he sells. He is the next Donald Sterling, it's obvious. But even Sterling wasn't this braindead.
Create PR hell for him and Nico. Start websites, more chants, louder chants, buy billboards, social media, youtube, boycott every part of the franchise, etc. This is a dynamic moment where you either fight for your team or you let it get hijacked by a categorical P.O.S. human who will f it up for 5, 10, 15 years. It's a predictable pattern when you have trash like Dumont owning the team.
One thing is for sure - as long as Patrick Dumont own the Mavericks, they will be a laughing stock franchise. Every employee, player, free agent, future draft pick, and fan already understands that after witnessing his moves, behavior, and his rhetoric. You may have glimmers of hope, but incompetence and corrupt leaders will eventually bring it back down. Don't expect anything at all to get better until he's ran out of town.
