Being a manager and being an umpire are two completely different things. You can't compare them since, obviously, there are way more things that go into being a manager than being an umpire. So why doesn't a defense of "he's a professional" work for managers? It's easier to see when an umpire screwed up. You can even watch it from multiple angles and in slow motion, something that doesn't work for managers and wouldn't help them anyway. How do you know that umpires aren't getting punished? Look at the NFL. Refs get graded down all the time for making incorrect calls but only the ref in the San Diego-Denver game getting graded down made news. And I'm sure umpires miss calls sometimes. I'm not arguing that they're perfect. What I am saying is they've got a much, much better grasp of the strike zone than some kid watching on TV posting on the internet. well, the fact that they're almost never fired for being bad has something to do with my thinking that they're not getting fired for being bad. After spending a few minutes looking around, I've found one story about a guy being fired for umping-related stuff and he was fired 20 years ago.
