If they were only going to sell if they got blown away, they'd never have publicly discussed it. I think the family wants out. Jim is done with it. His brothers never wanted it and Joe is an incompetent bafoon which the older ones now realize.
I think they were pretty far down the road with Ishbia when he pulled the plug, so it delayed things a lot. But if they have any sense, they will still take the next best offer and run. The public is as down on them as they've been since the contraction days and it will be even harder to recover. I don't really think they can.
