At this point I'm not going to move the needle one iota no matter how much I talk, so I'll just put up one post here. What will be, will be.
I will say that a SCOTUS appeal is unlikely to succeed by either side (as in the SCOTUS probably won't take the case), but is even less likely to succeed if Brady/NFLPA loses. If that's what happens, then this is just another ho-hum arbitrator's decision upheld, which is what the federal courts VERY strongly favor, so there isn't much compelling for the SCOTUS to look at.
The other thing to get out of this, either way really, is that the NFLPA will probably go to the mat, absolutely to WAR, over the arbitration section of the CBA. And the NFL may dig in its heels. Not knowing much else about what may at issue, I wouldn't be surprised to see a strike/lockout in 2020 or whenever the CBA is up for renewal over this. And it's pretty easy to see both side's positions on the matter. The NFL wants discretion to penalize player misconduct, while the NFLPA thinks Goodell does whatever he wants, whenever he wants, without notice or any regard for the rules in place or the history of how similar issues are handled in the past.
Finally, it's truly unbelievable we're still dealing with this more than a year later.
Carry on with your Pats hating, or Brady defending, as you prefer.
