I am looking at this whole fiasco from a different angle today. I think Brown was looking for support from the Raiders in his helmet fight. If you look at the details, the NFL did not list his helmet type as being on the list of disallowed. So he did not know he had to change it. When the Raiders did not support him, he started to get agitated because he sees himself retiring without a Superbowl. To add insults to his mental injury, they fine him for something he thought they were on the same page on with a letter. He thought they were "cool" and then they tell him his contract is no longer guaranteed and at that point he said **** it, I have money, I need a super bowl to solidify my career. I can't deal with this.
He may not be bat **** crazy crazy.
What I can't explain is the video taping of Tomlin's victory speech in the locker room. That one I can't explain. I am a bit crazy myself, but unlike him I have the ability of self reflection, so I can relate with Brown at lot and not totally.
