You're certainly entitled to your opinion, but it had nothing to do with guilt or innocence at that point. Brady lost because the higher court refused to interfere with the league's collectively bargained right to hear player appeals for discipline handed out by that same league. Doesn't seem fair or just to most of us, but that's current life in the NFL. As for the reduction of Hardy's suspension, it was done by Harold Henderson who works for the commissioner, not the court system. Rice's case was completely different. He won his appeal because Goodell suspended him for two games initially, then later increased it to an indefinite suspension. In that case, the arbitrator ruled that Goodell overstepped his bounds.
If the Commissioner decides to suspend Zeke, Zeke can certainly choose to fight it, but he won't win. I'm no lawyer or legal expert in any sense, but from everything I've read on the subject, that's the way it is. Again, you're certainly entitled to your opinion.
