These are mostly ad hominem arguments against his article. He's not saying anything we haven't already said here, it's not crazy at all what he's saying. That is, Berman's hands are tied for the most part legally speaking, and there is a good chance he sides with the NFL even though he realizes it is ridiculous. Of course there are other options, but this is one main option.
The Garvey case should give us all pause, no?
In terms of trying to overturn on the basis of fact finding yes but that's not the basis of the case.
United States code of law Title 9(arbitration) chapter 1 section 10
(a) In any of the following cases the United States court in and for the district wherein the award was made may make an order vacating the award upon the application of any party to the arbitration-(1) where the award was procured by corruption, fraud, or undue means;(2) where there was evident partiality or corruption in the arbitrators, or either of them;(3) where the arbitrators were guilty of misconduct in refusing to postpone the hearing, upon sufficient cause shown, or in refusing to hear evidence pertinent and material to the controversy; or of any other misbehavior by which the rights of any party have been prejudiced; or(4) where the arbitrators exceeded their powers, or so imperfectly executed them that a mutual, final, and definite award upon the subject matter submitted was not made.
It seems that since Goodell (I'll just call him RG1 going forward) is the prosecutor, judge, jury and appeals court it's not hard to argue that he engaged in "evident partiality".
The judge also implied that RG1 was guilty of misconduct by refusing to hear testimony of the coauthor of the Wells report. Certainly he could claim that is "pertinent and material".
Lastly, there is a defined penalty for equipment violations of a fine so it could be argued RG1 exceeded his authority by suspending Brady instead of going with the defined fine.
That's not to say that's what the Judge will rule but those type of factors didn't apply in the Garvey case which used a neutral arbitrator.
