The way you've worded that sounds more like "court of public opinion", which is different, but relevant.
The NFL fired him from his job, and it was way too soon after the alleged event for them to claim to be reacting to lower ratings or something like that. I can see Irvin suing for wrongful termination.
Thing is: if the NFL had any stones on the core of this matter, they would have hired observers to tail Irvin, and I'm pretty confident they would have found all the evidence they needed to legitimately fire him a long time ago.
A lot of it has to do with "if we don't know, we don't have to do anything about it".
Jimmy Johnson knew very well what was going on with the extracurricular activities of his players just as he did at Miami and OK State. He even made the hilarious remark in an interview that the thanked God that Barry was at OU at the same time". LMAO, Jimmy had some bad boys but Barry had borderline criminals and some did get charged.
That court of public opinion has a much better reach than the court of law. It has cost a lot of people their careers just in the past 10 years.
And one thing that Irvin said that a lot of people do not approve of was he couldn't remember because he'd had a few drinks. There are a lot of people in Dallas still mad they changed the drinking laws and made portions of the counties wet.
And even if you don't subsribe to that, isn't it just stupid to say that on the radio? Why not he was tired and met a lot of people that day, laying it on drinking was really stupid and part of the reason the NFLN has to deal with him.
