You're whole post was spot on. I wanted to add to the statement above.
Executors of wills and trustees of trusts are bound by the terms of the will or trust. They aren't like an executive in a company that gets to make independent business decisions. A will can't dictate who are employees of a company after the change of ownership occurs, so no will Benson wrote can dictate that Loomis has to be the GM.
A trust might be able to do that for the life of the trust. Has anyone given a credibly sourced report that Benson's trust dictates that Mickey Loomis remain the GM? Naming Loomis as a trustee does not automatically mean Loomis gets to decide if he's the GM or not. That's not how being a trustee works. I learned this as the co-trustee and successor sole trustee of 2 trusts my father created.
My dad did 2 really complicated trusts to control everything as much as he legally can after he dies. A will only gives you control over who gets what. It can't dictate anything other than that. A trust can give more control, but it has limitations too. Bottom line, you can't take it with you or completely control it when you go.
