Well, if both sides won't like what the 8th Circuit Court of Appeals has to say, they definitely won't like what Congress may. This notion that these owners are an aggrieved party being taken advantage of by 'greedy' and 'disgusting' players would be laughable if it wasn't so widely believed.
Here's what happens in the real world when a business model is unsustainable - the model changes. Now, locking out your primary labor force, negotiating in bad faith in order to force concessions is certainly one way to go and the owners have every right to try it. Until they are found in violation by a Court of law and those particular tactics prove less than effective.
The change in the model may very well be - teams in secondary markets that don't have sufficient Revenue streams, don't survive. Or move to where they can. But directing this at your Labor force - seems to be the wrong cure for the wrong illness.
