Well, the fact is that to say anyone other than Donald were making decisions like hiring the SD or Johnson, would be very shady in the eyes of the League - this is a legal point. Donald remains the owner until it goes through and it hasn't gone through, has it? So there is that.
As for whether you believe if will, its basically an act of faith. I would suggest that the fact we've hired the SD- and I would recommend his podcast interview - means the club is completely changing its approach, either way. If Donald is driving that - then good for him. However, I rather suspect he is not, given how against the grain it would be compared to the last 2 years of basic malpractice.
Important thing is that the approach has changed substantially. Like, if Donald has a head transplant and starts making good decisions, then who cares if he stays?
