This opinion is hilarious to me. The NFL has way more money and lawyers than the NFLPA, they chose the venue for the case to be heard in, and they still lost badly. So, explain to me how they lost if they had good lawyers. They should be able to get away with anything, right?
And before you think that this is about a burden of proof or anything, or that Brady skated simply because the NFL failed to prove its case, the deck in this case was very much stacked against Brady. His side had to prove that the process violated labor laws, his side had to get a federal judge to overturn arbitration, something which happens exceedingly rarely. The NFL's side was just asking the judge to stay out of it, which is usually what judges do.
The judge even says that he's assuming that the NFL's version of what happened is true (not necessarily because he believes that, but because it's what the law requires him to do). So basically, even if Brady did what they accuse him of, the punishment and appeal process were so badly run as to be against federal labor practices. Hell, he even ignores like half of the NFLPA's argument because he doesn't need it to overturn the case (seriously, he says basically "since these three things are enough to overturn, I'm not even going to discuss these other three things").
Brady didn't get off on a technicality, he got off because the NFL was found to be fundamentally unfair in how it handled the case. That's not some minor thing, and to pretend that this is a case of some guy beating a rap because his lawyer figured out a clever end around the justice system is ignorant and foolish. Is Brady's lawyer good? Of course, but it's fairly clear from the judgement that this wasn't about the quality of his lawyer, but about how badly the NFL has handled itself.
Whether you hate Brady or not, whether he cheated or not, doesn't really matter here. What matters is that a massively arrogant league office run by a guy who fashions himself a dictator with unlimited power got crushed by a federal judge. Frankly, most NFL fans should be happy with that, because maybe next time (and there will be a next time for someone else) the league will be a little more careful in how it metes out justice.
