Sounds to me like Perry Mills both knew their cushy jobs were at stake and they tussled over what to do. Doesn't sound like Perry had a free hand until the last 48 hours.
If your boss doesn't want to trade Morris, then you don't look into those deals much, especially since the Knix were also trying to move some of Portis, Jr. Smith, Ellington, Trier; willing to move Knix, Franc, Randle, Elf, Taj for the right return.
Yes, I'm speculating, but that's roughly how things likely went down based on what's leaked out.
Mills Brother wanted to keep and resign MaMo, so Perry was likely working on other deals with low level Morris talk in the background.
My theory is that cost us a potential better Morris return. While the intensive Morris trade focus right before the deadline might have cost us other deals (Portis, Smith, etc). Getting in on a 3 or 4 tram trade takes up significant time. HOU reportedly tried to get NYK in on their Covington/Minny deal.
I'm glad Mills is gone, but the timing and power struggle did us no favors.
