Yes, that.
I think too many people in the forum think a federal court case is going to be a de novo "let's re-do Brady's appeal in front of a judge this time and have him issue a final ruling on if there should be a penalty" case.
IANAL, but I don't think this works that way. First, I believe a Brady win will not be a ruling that he can't be suspended -- he won't get such a ruling. Rather, a win in this case would be a decision saying (a) that the arbitrator abused his discretion and/or was not operating according to CBA procedures, (b) vacating the abitrator's decision, and (c) requiring it to be re-arbitrated, preferably by (d) someone other than Goodell-bot.
Then we get to do the whole thing over again, perhaps involving yet another trip to federal court.
