The motion for contempt that the NFLPA filed depends on whether Goodell wanted to keep Peterson on the commissioner's list (players on this list still get paid, so Peterson didn't suffer much in the way of wage-based damages), or whether the Vikings wanted to keep him away from the team until the shitstorm settled a bit and requested he be kept there. If Goodell can show that the latter is true, the NFLPA's motion will fail. Mostly, this is just a case of the NFLPA being combative (and with good cause).

I still think the NFL will win it's appeal of the Doty decision, but it's academic at this point. It's a question of which precedent you apply. The precedent for courts to stand aside when two sides have agreed to binding arbitration, or the precedent of prohibition of retroactive punishment from being levied on employees by their employers (which certainly happened in the Peterson case). I think the arbitration precedent blankets the ex-post-facto precedent, so the league is in good shape. Even though Goodell is an arbitrary douche.
