On Charlie Rose, Matthews broke it down into a 5-item checklist, but the critical ones involving 'stories' et al was how removed/distant/insular/indifferent Bobo is in real life, how intractable he can be, and how he has no one willing to go to bat for him in the media. Insinuating Daley couldn't get close to the misfit and that's why he's out.
Daley leaving is a big deal, it leaves Jarrett in full control.
