Maybe. I have another theory... I have a close friend who is a very good businessman. He started flipping houses a few years ago and has built that into a company that is now building developments. He knows exactly what he wants to do and where he's headed. But he has one flaw (for lack of a better word) in that he never considers the possibility that something might not go his way. He only sees the best possible outcomes in his mind and becomes absolutely perplexed if things don't go the way he envisioned. I think Ross might fall into that category. He doesn't know what to do now because he never considered we could wind up here.
You could be right but I am seeing things a different way. Assume Ross wants to build a high rise apartment in the middle of a residential neighborhood of two story houses. The residents rise up to oppose what he is planning to do. So Ross changes his proposal to add some landscaping and the construction of a park to his high rise project. The majority of the residents still oppose building the high rise, but some are swayed by the changes. The question becomes whether enough people are swayed to allow Ross to build his building.
I think this story is a deliberate plant by Ross's PR people to see if adding a park to the proposal (firing Sherman) will change enough minds so that he can still build his building (which is to not fire Ireland or Philbin). He'll fire them to save his bottom line, but only as a last resort.
