I think they were/are reluctant to go the COO route with anyone after the Staggs disaster (yes, yet another succession mess). There was a link in the current article to the good article on how the whole Staggs thing went down.The initial idea of Iger CEO and Chapek COO probably would have been the ideal one...
Also unexplained in the article is what exactly happened with Christine McCarthy... There is definitely more to the story there as well....
Great point on McCarthy, it seemed like they were going to get into that drama and then nothing. And not any mention of the cooking the books accusations we heard on Chapek's way out the door. Just means we'll have to buy the book, I guess! LOL
