Managing up is probably one of the most important attributes of any leader who is deserving of promotion/next steps in their career.
If you can't manage up, you simply won't succeed. In Getz role, managing up now means getting his boss (ownership) to do uncomfortable things, sign bigger contracts etc. Never forget that the Padres weren't big spenders until Preller came in and sold ownership. Getz has the Sox running the lowest relative payroll since I followed the team.
People are celebrating Getz selling a vision to a guy he is literally offering a promotion too. The promotion alone is the most valuable thing he's selling.
It doesn't mean the guy isn't smart or capable. As I said, wouldn't have minded hiring him as our GM. Instead, that guy's now got an idiot above him that he has to overcome to succeed at his job.
